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 which 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. 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. ‘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. 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.

In our > 20 years of experience in selling electrical products for both domestic and commercial use, we have encountered a lot of questions from our customers both online and in our shop. Many of these questions are related to the choosing of the right bathroom ventilation fan. What does one need to know about the bathroom fan which he needs to install at home? What features he needs to make sure it has, so that he would have the latest in technology and in aspect? We asked our consultants on the counter here in our showroom in Archway and we checked the questions you have asked us online, and we compiled a list of such questions below. The Size of the Bathroom Fan The size of the bathroom or toilet fan matters. In general, for the domestic use people need mainly the 4 inch fan, 100 mm diameter (the extracting diameter / duct). The front lid / the grill is in general max. 158 x 158 mm - small, not taking too much space in the bathroom. The Fan Must have a Timer Many times we forget to turn off the light in the bathroom, and it is the same with the fan - it is better to make sure that the bathroom fan turns itself off in 2-3 minutes after you leave the bathroom. The timer module is many times incorporated into the fan, and it can be set up to the time lag desired. How Quiet is the Fan? It is very important to have a quiet fan, so quiet that you cannot even hear it! Some fans are so loud that you hate being in the bathroom with them running in the background :( while others like Airflow QT100T and Envirovent SIL100T are as quiet as 26.5dB(A) at 3m - you can barely hear the fan extracting the air! How Far is the Ducting? If the ducting needs to be longer than 3 meters, you will need a different fan with a stronger power of extraction. But in general, for domestic or regular office bathroom/toilet needs with ducting up to 3m (the length of the ducting until the outside / the central ventilation system). Ducting can also be purchased via Sparks. What is the Cheapest 100mm Toilet Fan? Many customers ask this question, and on our website, we have the PRO100T from Envirovent (100mm diameter, with a timer included). It is not the quietest among them all, but it is definitely the cheapest and most popular one! For those who are looking to invest in a quiet fan with a stylish look, the SIL100T and QT100T are the first choices. Extra: Dust Free Grill Dust tends to accumulate on the grill of the fan, and with time and use the fan needs to be gently wiped with a clean cloth (see the instructions included in the package). If you are looking for a fan that has a dust-free grill (no dust accumulating as time goes by) check out the Envirovent SILD10TW. It always stays clean! Was the above information useful?

When it comes to domestic ventilation, we all need help; thanks to Manrose, we now have a guide on, How to Choose a Ventilation Fan at Home. We read their guide and we would like to present the main points recommended by this ventilation fans manufacturer as it relates to ventilation at home. Ventilation is absolutely necessary, and it is good to know the following matters related to ventilation at home:What are the Problems caused by Poor or No Ventilation?What do Regulations say about Ventilation at Home?Where should we Install a Ventilation Fan at home?What Ventilation Fan is Required for the Minimum Air Changes Required per Hour?How to Choose the Right Ventilation Fan at HomeWhat options are there for Ventilation at Home?What are the Problems caused by Poor or No Ventilation?If the ventilation fans are not working or nonexistent, or if there is poor ventilation in a home, there are a few problems that may arise. First, there is the stale air which we all hate. Stale air can be caused by things such as cooking smells, odours remaining in the bathroom, a general lack of ventilation around the house, smoking, and a damp atmosphere. Stale air is not good for health and is very unpleasant to breathe.Stale air can cause a certain level of discomfort and poses a risk of respiratory illness and general poor health. Condensation is another problem caused by poor ventilation at home. When the steam from the kitchen or the bathroom spreads in the house and finds cooler surfaces around the house, there is condensation. We may try to conserve heat by sealing the windows and keeping them closed, therefore reducing natural ventilation; this causes more condensation. The consequences of condensation in a home include mould growth, peeling wallpaper, and even severe structural damage such as wood rot or dampness. What do Regulations say about Ventilation at Home?According to the Building Regulations Document F1 (2006 Edition), we know the importance of ventilation. Furthermore, these regulations stipulate that mechanical ventilation must be installed in kitchens, bathrooms (or showers), and toilets. The ventilation fans installed need to meet or exceed the current Building Regulations so that humidity is removed at the source before it can reach the cooler part of the dwelling. In particular, what is recommended and even required by the Building Regs are as follows:Intermittent fans - they operate on an "as required" basis and are turned on or off with the light switch or via other control (such as a pull cord switch). These are the regular fans installed on the wall or ceiling that provide high extraction for a short period of time when turned on. In the bathroom or shower room, the regulations require a fan capable of extracting min. 15 litres per second when installed. In a toilet, separate from a bathroom, the regulations require a fan capable of extracting a minimum of 6 litres per second when installed. In the kitchen, the regulations require a fan capable of extracting min. 60 litres per second when installed. And in the utility rooms, the regulations require a fan capable of extracting min. 30 litres per second when installed. Continuous Fans - they work all the time to extract excess moisture and stale air at low extraction rates throughout the day, and they have a boost function when humidity levels rise. They are becoming more common, for they ensure better indoor air quality while using less energy than intermittent fans, thus being more cost-effective to run. The Regulations regarding these in terms of air extraction rates are as follows: in the bathroom or shower room - min. 8 litres per second, in the toilet (separate from a bathroom) min. 6 litres per second, in the kitchen - min. 13 litres per second, and in utility rooms - max. 8 litres per second.Buy Manrose 100mm Bathroom FanWhere should we Install a Ventilation Fan at home?The location of the ventilation fan is very important; it is of utmost importance to site the fan correctly. A ventilation fan needs to be always sited in the furthest window or wall from the main source of air replacement in order to avoid short-circuiting the airflow. Also, it needs to be located as high as possible in the window or wall nearest to smells or steam, but not directly above eye-level grills or cooker hoods. If a room in the house contains a gas boiler or any other fuel-burning device with a non-balanced flue, it is imperative that there's enough replacement air to prevent fumes from being drawn down the flue when the fan is extracting to its utmost capacity. Furthermore, according to the IEE Regulations in the UK, conventional mains voltage fans in a bathroom or shower must be located in places where they cannot be touched by a person using the bath or the shower, as well as away from any water spray. SELV fans (Safety Extra Low Voltage Fans, 12V fans) are specifically designed for safe ventilation of toilets, bathrooms, and shower rooms. They can be fitted within the area with splashing water (see their full specs) without any risk of electric shock. Buy Envirovent Design 100 Bathroom FanWhat Ventilation Fan is Required for the Minimum Air Changes Required per Hour?When considering where and what fan to install in a particular room at home, we need to know what is the minimum air changes required per hour. In order to calculate the correct air changes required for a room, you need to know the room volume in cubic metres, which is basically the length x width x height of the room, which needs to be multiplied by the number of air changes required. According to the current Building Regulations, here are the minimum air changes required per hour:Bathroom & Shower Rooms - 3 air changes/hBedrooms - 2 air changes/hCafés - 10 air changes/hCanteens - 8 air changes/hCellars - 3 air changes/hChanging Rooms with Showers - 15 air changes/hConference Rooms - 8 air changes/hGarages - 6 air changes/hHairdressing Salons - 10 air changes/hHalls & Landings - 3 air changes/hHospital Rooms - 4 air changes/hLaundries & Launderettes - 10 air changes/hLiving & Other Domestic Rooms - 3 air changes/hMeeting Rooms - 4 air changes/hOffices - 6 air changes/hRestaurants & Bars - 6 air changes/hSchool Rooms - 2 air changes/hShops - 8 air changes/hSports Facilities - 6 air changes/hStore Room - 3 air changes/hToilets – Domestic - 3 air changes/hToilets – Public - 10 air changes/hUtility Rooms - 15 air changes/hWorkshops - 6 air changes/hHow to Choose the Right Ventilation Fan at HomeIn light of all the requirements and specifications above, we need to find out in particular how to choose the right ventilation fan at home. When we choose the right ventilation fan, we need to bear in mind the types of air extractor fans and the types of switching/turning on for the fans available. Buy Airflow Quietair Bathroom FanType of Air Extractor Fan for HomeAxial Fans - the axial fans are designed to move air over short distances of up to 2m ducting. For example, you need an axial fan if you install it on the wall, the window, or the ceiling and the exit is straight through or the ducting is under 2m long. The axial fans come in 4-inch (100mm, the most popular ones), 5-inch (125mm), 6-inch (150mm), and larger sizes.Centrifugal Fans - these are designed to move air over longer distances, performing well against the pressure caused by longer lengths of ducting and resistance by grilles. They are not as popular as the axial fans but sometimes are recommended to use. When ducting vertically, it is recommended that a condensation trap is used. Type of Switching On/off for the Ventilation FansStandard ventilation fans: the standard model fans are wired to the wall switch for remote switching through either a wall light or a separate switch. They are the most common ones. Timer ventilation fans: the timer models have a built-in adjustable time delay operated by the light switch. The time delay can be adjusted at installation, and these are suitable for locations where you need some extra ventilation even after the light is turned off. Pull-cord ventilation fans: the pull-cord fans have a pull-cord switch to be turned on/off when needed via this means. Humidity ventilation fans: the humidity models with built-in adjustable sensor turns the fan on when a certain threshold of humidity is sensed. They are automatically turned ON or OFF when the humidity sensor detects the humidity levels. PIR or Microwave Sensor ventilation fans: the PIR models are sensitive to movement. When someone enters the room, the fan turns on, and when presence is not detected, it is turned off.What options are there for Ventilation at Home?On our website, we have a wide range of ventilation systems available, and the three main manufacturers we distribute are Airflow, Manrose, and Envirovent.
