How Airflow Ventilation Solutions deal with Indoor Air Pollutants at Home

Problems caused by bad air quality in our indoor environments can be devastating. Recently, the World Health Organisation (WHO) published a report that showed that the air we breathe has become polluted with cancer-causing substances. The mixture of exposure to indoor and outdoor pollution has led to 6 million people dying annually. Considering that people now spend up to 90% of their time indoors, it is likely that indoor pollution played a significant part in this terrible statistic. What are the causes of indoor pollutants? Many factors contribute to poor levels of indoor air quality. Outdoor air gains entrance through windows, doors and the general ‘leakiness’ of buildings that are not well insulated. One of the main culprits is biologically produced pollutants. People release pollutants through their normal metabolic process. They also use products and appliances that emit toxins on a daily basis. The appliances we commonly use at work or home are a significant source of pollution. These include cookers, boilers and portable gas or paraffin heaters. These items are very damaging to the quality of indoor air that we breathe. Condensation is one of the largest causes of dampness in indoor areas, and can eventually lead to the growth of mould. The health problems associated with mould must be emphasised: they can lead to a litany of ailments. Prolonged exposure to high levels of indoor dampness can reduce lung function and cause chronic health problems such as asthma. If those who already suffer from asthma are exposed to dampness, they have an increased likelihood to develop more severe symptoms. Mould can lead to various other medical conditions, such as pneumonia. According to the World Health Organization (WHO), a considerable proportion of the world’s 300 million cases of childhood asthma is attributable to indoor dampness and mould. We here at Sparks are sure you’ll agree air pollutants must be effectively dealt with. This needs to be done before they can inflict damage to our homes and health. Residential ventilation solutions offered by Airflow Thankfully, Airflow offers a wide range of residential solutions. They are one of the UK’s leading manufacturers of ventilation products for your home or property. They have been making innovations in ventilation for decades - since they started out in 1959. Their first product that made waves in the industry was the Loovent, which went on to become a best-seller. This range has sold over 1 million units and is still extremely popular to this day (it has been updated with modern features now, of course). The Loovent Eco is a powerful centrifugal fan that boasts a modular design. This makes the installation and maintenance of the device very easy. Furthermore, they produce minimal sound levels and operate with great eco-efficiency, powered by a low-energy motor. The Loovent Eco comes in versions that include a pull-cord, humidity timer, motion sensor (with timer), a delayed start of two minutes and two-speed settings. This product is ideal for long stretches of ducting, as it will maintain pressure over the full length of a duct run. It is recessed or surface mounted so can be mounted practically anywhere you desire. The QuietAir is another successful range developed by Airflow, with the QT100 being a real stand-out in terms of popularity. The QT100 is an axial extractor fan that combines contemporary design with ultra-low noise levels. It was awarded the Quietmark in 2014 by the Noise Abatement Society as it operates at a lowly 25 decibels (dB). Its features include a long-life ball-bearing motor with 40,000 hours of operating time. It can run at two speeds and has an adjustable overrun timer. Furthermore, it uses a high-efficiency impeller that helps to keep running costs low; it only has a power consumption of 5 watts.Buy Airflow Quietair Fans Then, there is the iCON range - one of the first products to introduce the plug-in module concept to the extractor fan market. iCON’s revolutionary design ensures effective ventilation; the low-energy fans are quiet and use a minimal amount of energy. They also come in Safety Extra Low Voltage (SELV) versions, which provide extra safety and peace of mind at home. The design includes the option for installing a plug-in module, which enables you to adjust the fan to suit your specific needs. Their round, slim design means it is a breeze to install the device in either a wall or ceiling. With three versions (the iCON15, iCON30 and iCON60) they are suitable to install in any room, whether it be large or small. The enduring popularity of the iCON range led to the release of the high-tech iCONstant. The iCONstant is among the quietest extract fans on the market (with a sound level of 21 dBA) and costs less than a lightbulb to run for an entire year. You can choose from a Timer version or a Humidity Timer version of the product, depending on what you find preferable. The ‘constant’ in the name of this product is taken from its ability to constantly extract damp air. Though they can be used in any room, Airflow designed the iCONstant with toilets, bathrooms and kitchens in mind. This is because these are the areas of your home that will produce the most moisture, which could lead to damp and mould. One of the iCONstant's main purposes is to keep you healthy by maintaining clean air quality within your home.Buy Airflow iCONstant Fans ‘Extract and replace’ - how Airflow helps you keep a healthy home Airflow has always aimed to produce healthy breathing air through energy-efficient means. This is demonstrated by the history of their products, looking at the iCON60 fan, for instance. The iCON60 is the largest in its range, and designed to be compatible with larger residential spaces. They are highly efficient in areas such as residential lounges, domestic kitchens, changing areas and utility rooms. Airflow understands the importance of ‘Residential Heat Recovery’ and how it relates to people’s well-being. They know that an effective ventilation system in a dwelling will protect the occupants - and the building itself - against harmful levels of condensation. Condensation is more likely to occur in residences where large groups of people live. This is because every individual does their share of cooking, washing and bathing. With their varied range of products, Airflow provides effective ventilation with heat recovery for the supply of controlled, crisp and filtered air.Heat Recovery Fans at Sparks They manage to do this while eliminating harmful moisture and airborne pollutants. Whether you live in a house, student halls, a flat or another type of residence - Airflow will have you covered. They offer an excellent variety of ventilation products to help save you energy and - more importantly - make sure you breathe proper air, the good kind of air. They have done this for five decades now and the endurance of their brand attests to their success.

How Decibel A-Weighting Works and Why It's Important for Fire Alarms

If you've taken alook through our Fire Alarms and Ventilation systems (maybe it's a slow afternoon at the office), you might have noticed that sometimes we give a dB(A) value in the technical information, under something like "sound output." This fire alarm sounder has a sound output of 101 dB(A); on the other hand, there's an extractor fan with less than a quarter of the sound output, at 25 dB(A). Measuring Noise dB(A) stands for Decibel A-weighting - it's a measurement of the level of sound pressure in the air. That measurement is modified so that the measured loudness matches the loudness that is perceived by the human ear as closely as possible. This is opposed to a straight, physical measurement of the sound pressure in the air; the people in charge of taking the measurements try to ensure that the perceived sound stays reasonably constant in all environments. (Strictly speaking, this isn't always possible for a huge number of reasons, but it's close.) Our examples are human-centric applications, after all; workplace noise measurements are also expressed in dB(A) in order to comply with regulations. An A-weighting filter de-emphasises the lower frequencies (pitches) of a sound and emphasises those around 3000-6000 Hertz where the human ear is more sensitive. For the physics geeks in our readership (and we assume there must be a few), Wikipedia has a good primer on the subject of decibel A-weighting, with curves and equations. This gives an easy, single-number measurement of noise level that we can compare with the noise level in the environment. When we need to install a fire alarm, to carry on with our examples, it should be louder than the ambient noise.Silent Ventilation fans at Sparks Using Noise The alarm sounder we mentioned above has a sound output of about 101 dB(A), which is a little bit louder than a newspaper press. The "ultra-quiet" ventilation fan is about as loud as a person whispering to themselves in an art gallery. The measurement in dB(A) allows a contractor to compare the sound output of a thing with the environmental noise level: if the sound output of an alarm sounder is higher than the general level of noise, then the alarm will be heard. If the source output is lower, then it will be masked. Sometimes, the distance from the source is also given. This is useful - even essential - for larger environments, where an alarm sounder might be installed far away from someone working at a factory machine, for instance. Generally, as the distance doubles, the sound level in dB(A) is halved. This should be taken into account when installing an industrial alarm system. Broadly: you'll want to go as loud as possible with the fire alarms (ideally without damaging anybody's hearing!), and as quiet as possible with ventilation fans and other such appliances. It's an interesting experiment and it opens up a whole new can of worms (as if we didn't have enough already) - how loud is your office? Your house? Are you using the right appliances for the noise level?

Advice: How to Deal with Condensation and Mould at Home

There are many guides on how to deal with condensation and mould at home, and you can never be too much in advising people what are the dangers of having mould in a domestic environment. As the temperatures outside drop, it is easy to have condensation on the windows and then mould growth in different areas in the house. Especially between the months of October and March in the UK, there's a high likelihood that condensation and mould formation would increase. If your windows look steamy or with condensation on them in the morning or sometime throughout the day, you need to deal with the problems. If you are experiencing condensation and mould on windows, walls, or ceilings, you need to determine the cause for this and also take care of the problem as soon as possible. When mould grows on the wall, on the window, or on the edges of the window or wall, you shouldn't think there's a problem with your house but rather, there may be a problem with ventilation. Immediate action needs to be taken when mould growth is detected.Keep reading to find out more concerning how you can deal with condensation and mould at home, in particular:Condensation: Though Unavoidable, it can be Taken Care of!Excessive Condensation can Lead to these ProblemsMoisture and Condensation: how to Produce Less Moisture!Preventing Mould Growth by Reducing Condensation: Ventilation!Hot - Cold - Ventilation - Let the Air Circulate!When there is Mould Growth: How to Clean MouldFurther Reading on How to Deal with Condensation and Mould at HomeCondensation: Though Unavoidable, it can be Taken Care of!What is condensation and how does it form, or what are the causes for condensation? As we live our lives in our homes, especially during the colder months of the year, condensation may appear on the window or on the wall. There's always some moisture in the air, even though we can't see it; when the air gets cold, it cannot hold the moisture and tiny droplets of water are formed on the windows - especially in the morning. This is condensation. It is nice and warm inside and it is very cold outside; it is easy for condensation to appear. When you take a shower, for example, the mirror or the bathroom tiles may have condensation since the cold surface of the mirror is hit by the air loaded with tiny water droplets. When condensation forms inside your home, it can become a problem unless you take swift action. It is unavoidable to have condensation but you can take care of it! Excessive Condensation can Lead to these ProblemsIf condensation is not taken care of swiftly, it can lead to many problems. Dampness caused by excessive condensation can lead to mould growth on the window frame, the window sill, the ceiling, the furniture, the wall, or even on the clothes. Damp and humid conditions also are the best environment for dust mites to easily multiply, thus affecting those suffering of asthma. This is why we say that, though unavoidable, we need to take swift action when we see condensation forming. Dealing with Condensation - First StepsThe first and easiest step to deal with condensation is to wipe dry the surfaces where condensation forms. For example, when you see condensation on the window or the windowsill in the morning, you can wipe these surfaces dry. You can take a dry cloth and wipe the wet surfaces clean, and then squeeze the water out in the sink. Don't be tempted to let it dry somewhere and do not put it on the heater, or else the water will go back into the air! And the second step you can take to deal with condensation is simply to ventilate the place; open the window for a bit until there is some ventilation taking place, and then the window can be closed later. Don't Forget to Ventilate!Dealing with Mould Growth: First StepsIf there is mould growth on the window, the windowsill, the wall, or any other surface, the first thing to be done is to limit the amount of condensation in the room and kill and remove the mould. Ventilation is necessary to get rid of the moisture in the air. To deal with the mould, the surfaces with mould growth need to be wiped down or sprayed with a fungicidal wash or very diluted bleach. Please follow the instructions as per the bottle of the cleaning product to make sure you do not get sick or destroy the surface to be cleaned. Moisture and Condensation: how to Produce Less Moisture!Simply by living inside your home, moisture is produced. Our breathing adds to the moisture, our activities add to the moisture, and everything we do can add to the moisture. And moisture leads to condensation, which can lead to mould growth. For example, when we sleep at night, just one single person can add up to half a pint of water to the air overnight! For example, here are some approximate statistics regarding moisture and how much it is produced:Two people at home, just by breathing, can produce up to 3 pints per day.Taking a bath or a shower can produce up to 2 pints. Drying the laundry indoors can produce up to 6 pints.Cooking and using the kettle for tea can produce up to 3 pints.Washing the dishes in the sink can lead to 1 pint of water.If we add all these together, simply by doing the normal things around the house (without ventilation), up to 15 pints of water can be produced just by two people. How can we reduce the moisture at home? Here are some tips:Dry your laundry outside. Hang your washing outside in a clean and dry place if possible, or hang it in the bathroom with the door closed and the window slightly open or the extractor fan on. If you dry your clothes indoors next to the radiator or the heater, the moisture in the air will increase. When cooking, cook with pan lids on, and turn the heat down once the water has boiled. Using a hob when cooking also helps extract the moisture, and using less water when boiling and cooking will help reduce the moisture in the air. Also, ventilate! Simply by opening the window, ventilation is produced. Instead of drying clothes inside the house, use a tumble dryer if possible. Or if you don't mind the extra cost and you have a laundromat not too far from your house, it may be worth it to pay and dry your clothes there. When running a bath, if you want to take a bath, it's best to run the cold water first and then the hot water, since this will reduce the steam by 90%. When taking a bath or a shower, always turn on the bathroom fan. Do not be tempted to keep the temperature steamy and warm in the bathroom: always ventilate! And after taking a shower, it is best to wipe clean the bath tiles, the mirror, and the shower so that less water may evaporate and become moisture in the air, leading to condensation. Preventing Mould Growth by Reducing Condensation: Ventilation!The understated free action we all can take in order to prevent mould growth by reducing condensation is ventilation. When we ventilate properly, condensation is reduced and it becomes more difficult for mould to grow. There are many whole house ventilation systems that can be set up, which can cost you a lot of money, but at the same time, simple ventilation can help and is easier to do! For example, cross-ventilating the home helps very much! Since it is so cold outside, you can slightly open one window downstairs and another upstairs, making sure the doors in between are open. Or you can open the windows in the rooms on the opposite sides of the house, making sure the interior doors to the rooms are also open. Allowing the fresh air to come in and circulate throughout the house can remove moisture. We recommend such cross-ventilation to be carried out for about 30 minutes every day. Tip: do not leave your windows open when you leave the house - this poses a security problem!Here are some other simple tips on ventilation at home:Open the trickle vents in the widows: many of the double or triple-glazed windows have trickle vents, usually located at the top side, which can be closed or open. It is recommended to keep them open during the day to allow air to circulate. Ventilate the kitchen when cooking or washing up. Simply opening the window and having the air circulate makes a great difference to condensation. Using a cooker extractor hood also helps. Use the bathroom extractor fan and make sure it runs more than the time you take a shower or a bath. Many extractor fans are affordable and they extract a lot of the moisture in the air. Open the curtains during the day, especially when opening the window, to allow the air to circulate. If the curtains are not open, condensation can happen and mould may grow. When using the shower or taking a bath, close the door and turn on the fan or open the window. When cooking in the kitchen, close the door and open the window, even turn on the hob. When the bathroom and kitchen doors are closed as different activities are taking place in those rooms, moisture cannot travel in the other rooms in the house.Do not overfill the wardrobe and cupboards and keep them at a small distance from the wall. Beds, wardrobes, and cupboards can have moisture on them and even mould growth if there's no ventilation between them and the cold surface of the wall. It is recommended to keep a small gap between large pieces of furniture and the wall. Ventilation Fans for HomeHot - Cold - Ventilation - Let the Air Circulate!Many of us love it when it is nice and warm at home, especially during the cold months of the year, so we keep the window shut and we may even appreciate the heat coming from the kitchen when cooking takes place. We need to remember that warm air can hold more moisture than cooler air, and droplets of condensation can appear on different surfaces around the house. The warmer the air is, the more moisture it can hold, like a sponge. It is best to have a medium level of heat throughout the house than to have one room extra warm and the others cold. It is recommended to keep the heat on low all day, especially in the cold months, rather than having it on full blast for several short periods during the day. If there's no heating in particular rooms, instead of keeping the doors closed, it's best to open the doors to allow some heat to enter into them and for air to circulate. Remember: the lasting cure for mould is to reduce the amount of condensation you create by using the heating, cooking, showering, etc, and by ventilating your home effectively!When there is Mould Growth: How to Clean MouldSome people do not want to ventilate nor do they turn on the fan in the bathroom during or after the shower, and the next thing you know, not only condensation happens but even more, there is mould growth. This is not the end of the world, but unless treated and removed, mould can grow and become quite dangerous to our health and the health of those in our homes. Here are some tips on how to clean mould when it grows in your home:Open the window and ventilate the room before doing anything. Chemicals may be used to remove the mould, so the fumes can be quite toxic; opening a window and turning on a vent or fan to ventilate the room is recommended. If it is too cold outside, still open at least one window to allow the air to circulate in the room. And if it is freezing cold, it's best to wait for a sunny dry day to treat the mould. Be aware that, since mould grows best in moist areas, it's best to regularly ventilate and, if you want to remove it, it's harder to do so when it is raining. Use protection when dealing with mould: facemasks, gloves, and protective eyewear. Whether you have asthma or not, it is easy to breathe in the mould spores when treating mould, so it is best to put on a facemask, gloves, and protective eyewear. The fumes of the cleaning products also can irritate your eyes, skin, and airways, so it's best to be protected. And wear a long-sleeved top and trousers to protect yourself. Read the instructions of the cleaning product. You may use bleach (low concentration) or other chemicals; before doing anything, read the instructions very carefully. Some of the cleaning products can contain harsh ingredients which, when used incorrectly, can be harmful to your health or can damage the surface you want to clean. Read the manufacturer's instructions. Never mix bleach with ammonia, for when these are mixed together, they create toxic fumes that are hazardous to health. Read the labels and, if possible, avoid combining cleaning products altogether. Throw away absorbent or porous items that are mouldy. The mould spores can get into the pores of the material and can continue to grow even after you clean that item, so it's best to throw it away. Things such as drywall, upholstered furniture, carpet, rugs, ceiling tiles, art, etc that have holes in the surface or absorb liquids, all need to be removed. If it can be washed, you can salvage it. Kill the Mould on Surfaces by choosing the right treatment. Some of the options include bleach, white vinegar, baking soda, or even dish detergent and water. The bleach needs to be diluted and properly handled. White vinegar can kill the mould as a natural treatment (especially when it is not diluted). Baking soda is also a natural option, and it also removes odour (dilute it and spray it on the surface). Finally, simply using diluted mild dish detergent and warm water with a brush can deal with mould. You can scrub the mould with soap and water to clean the surface. It is recommended to read the instructions, the way to prepare and scrub, and how to do it for each of these treatments. Properly treat the mould by spraying the solution on it and allowing it to sit for 15 minutes to one hour so it penetrates the root. Don't spray it and scrub it: spray it and wait. Treatments that are harsh, such as bleach, hydrogen peroxide, and ammonia work quickly. Natural treatments such as white vinegar, baking soda, borax, or tea tree oil may require longer to work. Follow the instructions and apply more than once. Scrub the surface with a stiff-bristled brush, if necessary. When all the mould is removed, it is good to scrub the area with soap and water, and even scrub it with a bristle brush. If the mould is removed simply by scrubbing it, it is good. Rinse and dry. Do not leave the area wet. It is recommended to use clean water to remove the remnants of any cleaning solutions, and then pat the area dry with a clean towel. If you are unhappy with the results, you can try the whole process again. However, if you want to try a different cleaner, it is best to thoroughly rinse the affected area to remove any remaining residue from your cleaning solution, and then let the area dry before you try again. Make sure that the area is clean after being treated. Best ventilation solutions at SparksFurther Reading on How to Deal with Condensation and Mould at HomeThe above guide is compiled from a wide variety of guides and advice leaflets put out by many entities, to which we are thankful.
