Os purificadores de ar para alergias realmente funcionam?

With numerous air purifiers on the market, finding one that can function as an effective tool in your allergy management plan could be bothersome. Knowing the answers to the following 5 questions before you purchase will mean using a cleaner that can allow you to feel better in your house or office.

Which technology is best?

High efficiency particle arresting (or HEPA) technology is used by physicians to assure clean air, and is the ideal way for office and filtration also. By definition this procedure will eliminate airborne allergens down to.3 microns; using a micron being defined is 1 millionth of a meter. How do I tell if it is going to get rid of the allergens that affect me? Different filters are designed to remove unique allergens so this is critical information to get.

HEPA filters using a multi-tiered filtration procedure will eliminate contaminants as small as.3 microns (household , and mildew spores, pelo e , pollen, germs, and viruses) but a good one will also have an internal filter that targets other contaminants also such as and smoke, or airborne volatile organic chemicals, as well as pet odor.

Check the technical specifications to pinpoint precisely what the cleaner’s filter is designed to eliminate, and if you do not see it there, call and ask the company to be certain it will do everything you want it to. How much space should it be able to wash? It’s always better to oversize your unit for the area as opposed to undersize it. Measure the space that you wish to wash and include ceiling heights greater than 8 ft as additional area on your calculations.

Then start looking for a purifier which has the capability to wash that square footage or slighter greater. If you don’t shut doors to your area, the cleaner will finally pull air from all over, so take care to measure accurately. As an example, if you’re purchasing an air conditioner for a bedroom, if you don’t shut the door, it is going to pull air from all around your house. If the area of your property is greater than the purifier is designed to clean, the outcomes will be less than successful.

Careful to issues like these will guarantee effectiveness. How often should I expect to need to change the filter? This is a excellent answer to get before you purchase the purifier as the price and frequency of replacing the filter will immediately affect your out of pocket expenses. Look for a purifier which has a 5-year filter life, and a prorated filter guarantee.

Only needing to change the filter after every five decades significantly reduces your operating costs, so you’re more inclined to use it without worrying about how much it will cost you if the filter fills up.


Look for a purifier which has a prorated filter guarantee also. This gives you assurance that if anything go wrong with the filter prior to the 5 year warranty runs out, you still do not pay full cost for the replacement. How long should it take to work? For those who have sized the unit properly for your area, and you run it on top for the first few hours, then turn it back to medium or low and leave it on 24 hours a day, you should see a difference rather quickly. Again this will depend on what you’re attempting to eliminate from your atmosphere, and the number of contaminants that have built up in your atmosphere. The trick to success is to get the filtration be constant instead of turning it off and on.
