North America’s shale gas boom is now so big that that it is now visible from space. According to a report by the Financial Times, the volume of unwanted excess gas being burnt off is increasing so quickly that shale fields can now be easily identified in night-time satellite photography, leading to concerns about wastage and environmental pollution.

Most families have done without an air purifier for generations – hundreds or even thousands of years. So what, you may be asking yourself, is the hurry to get one now? And it is true, there is a bit of a buzz about air purifiers at the moment. But do they work all right and are they worth the money? The answers to both of these questions are not straightforward, but everyone would have to agree that the motor revolves when you plug them in, so in that sense they do all work. Whether they are effectual or not depends on which model you buy. There are some very useful air purifying units and there is a lot of rubbish too. The very useless ones are the very cheap models, that are just not powerful enough and do not even enclose adequate filters, but leaving those aside, there are very good portable air purifiers and very good central air purifier systems. So, the first thing you have to decide is whether you want a central or portable air purifying system. If you want to purify the air in your office at work or your caravan or trailer, then a good portable purifier will do the job very well. The reason why a portable purifier is not so good for the home is size. Your house is just too large for one portable air purifying unit. If you locked yourself up in one room, then OK, but as soon as you open the door, or someone walks into the room, you have lost a lot of your decontaminated air. Therefore, if you are thinking about purifying the air in your house, you really ought to go for a central system, particularly if you already have ducting in place for a central heating or central air conditioning system. If you are fortunate enough to have such a system then a powerful and very efficient air purification unit can be fitted near your existing blower in minutes in most cases. These systems will purify the air in your whole home at the same time, which means that you can walk about your house, go about your daily business and leave interconnecting doors open at leisure. It is the only way to go if you have active children. This is often the cheapest option too, believe it or not. If you are going to buy a portable model, note the dimensions of the largest room you are likely to use it in and work out the volume of air in that room (length x width x height). You will have to check that whichever air purifier you get can handle that volume of air. That information will be in sales literature. The cost of filters is an important aspect in the overall cost of a purifier. How much are they and how often do they have to be changed? Can they be cleaned a few times before requiring to be replaced? Think about why you want an air purifier. Is it because you want to combat a specific allergy? Is it because there is a smoker in the house? Is it because of animals? Or is it just because of increasing levels of general pollution from cars and industry? Whatever the reason, make sure that the air purification system you are thinking about buying can take filters that can remove those substances from the air. Not all filters are identical – not all filters can filter everything.

Are you, or is someone in your family suffering from indoor air pollution? Is your family suffering from allergies, asthma, and frequent headaches? Indoor air pollution in your home may be the prime culprit. Indoor air pollution can be caused by: • Dust • Mold • Pet hair and dander • Residue from dust mites • Volatile organic compounds These pollutants and allergens are found throughout the home in and on places like mattresses, furniture, carpets, cleaning products, paints and adhesives to name a few. Many homes are designed to save energy by reducing ventilation. But when ventilation goes down, indoor air pollution can actually go up because pollutants are trapped indoors. When it comes to controlling Indoor Air Quality, carpet is actually a good thing to have. Unlike hard surface flooring, carpeting can filter and hold allergens for removal by proper cleaning instead of letting these pollutants become airborne. Now that you know these contaminants exist in virtually every indoor residential and commercial environment, what can you to improve the IAQ in your home? Here are some guidelines that can significantly help: 1. Clean plush furnishings (upholstered chairs, sofas, carpets and bedding) on a regular basis. This will reduce the presence of dust mite allergens that can cause health problems once they become airborne. 2. Control moisture levels with a dehumidifies, air conditioner or heat pump. Dust mites can only live in environments where the relative humidity exceeds 50%. 3. Keep interior surfaces dry. Repair leaks promptly. Mold naturally grows on surfaces that are moist. 4. Open windows when possible to increase air flow. If you are sensitive to outside dust pollen or molds, consider installing an air-to-air heat exchanger with an air cleaner on your home heating and cooling system. 5. Change furnace air filters often with fine filters that trap microscopic dust. 6. Vacuum carpets and floor coverings regularly with an upright, revolving brush vacuum. Concentrate vacuuming near often used furniture. Make sure the vacuum bag is clean and in good condition to keep airborne pollutants to a minimum. The use of a vacuum with micro or HEPA (High Efficiency Particulate Air) filtration designed to significantly decrease the amount of airborne pollutants emitted back into the air is highly recommended. 7. Have your carpets and area rugs professionally cleaned at least once a year with a “Green Seal Certified” dry extraction carpet cleaning system. Why should carpets be cleaned with “Green Seal Certified” dry extraction? Unlike typical chemicals used in carpet cleaning, “Green Seal Certified”" dry extraction cleaning compounds are all natural, nontoxic, biodegradable and are 100% safe for people, pets and the environment. They are also safe to use on all types of carpets and rugs, including natural fibers like wool, sisal and jute. Ask your carpet cleaning professional if the products they use to clean your carpets are WoolSafe® approved, USDA BioPreferred™ and Green Seal Certified. No Wet Carpets Since dry extraction carpet and rug cleaning inherently incorporates a low-moisture cleaning process, there is no waiting for wet carpet to dry. Rooms are ready for use as soon as the cleaning is complete. And, unlike wet cleaning methods, dry extraction cleaning does not increase humidity levels, so there is no risk of mold and mildew growth or damage to your carpet from shrinkage or split seams. The Natural Solution to Indoor Pollution Research studies have shown that one cleaning of carpet by dry extraction reduces: • Dust mites by 78% • Dust mite allergen by 75% • Mold spores by 85% • Cat allergen by 85% When it comes to improving Indoor Air Quality, remember that drier is always better.
