Air filtration is a very important part of maintaining your indoor air quality. Proper, effective filtration can greatly reduce the amount of potentially harmful contaminants and pollutants in your home’s air.
But how do you make sure the filtration equipment you’re using is adequate? After all, walk into any grocery or hardware store and you’ll likely see row upon row of air filters. Make no mistake, though; not all filters are alike, and some are much more effective than others when it comes to filtering out particles that can impact the air you breathe.
Which air filter is right for you?
Do you know MERV?
MERV ratings (Minimum Efficiency Reporting Value) measure a filter’s ability to remove particulates from the air. They range on a scale from 1 to 16; the higher the rating, the more effective the filter is at collecting particulates.
First, be aware there are several types of filters you can buy. They range from cheap to a bit more costly.
But it’s not so much the price you should look at as it is the fine print on some of the filters. Here’s what you need to know – ideally, you’ll want filters that are effective in picking up particulates that are less than one micron in size.
OK, you say. But what the heck is a micron? And how do I know if what I’ve got in my house is less than a micron? It’s actually pretty simple. As you can probably guess, a micron is pretty small – real small, actually. Most household particulates – dust mites, for example – measure less than one micron in size. You can’t see them with the naked eye. An air filter rated one micron or below can remove dust, pollen, smoke, pet dander and more. Many of those air filters you see at the local grocery store are not built to remove particulates that small. So you need to be careful about the type of filters you purchase. One inch filters, 4 – 5 inch filters – neither of these are very effective at removing the types of particles you want them to remove.
