Air Filtration System Basics for Homeowners

According to EPA studies, indoor air quality is often even worse than outdoors. So while you might worry about smog and pollution when you leave your home, you should know that on average, your interior air is probably about 2-5 times more polluted than the air outside. In some cases, it was found to be over 100 times more contaminated with pollutants. This could have something to do with a lack of fresh air, poor ventilation, and a plethora of particulates like dust, dander, bacteria, chemicals, and even mold or mildew. And there are several steps you can take to combat poor indoor air quality. For example, you can clean frequently (with green cleaners, no less), remove plush surfaces that trap and release allergens, and select an air filtration system that will help to clean your interior air.

If you are unfamiliar with air filtration (or purification) systems, there are a few things you’ll need to know before you purchase one for your home. First, you should know that there are two main options to choose from. You can either go with portable units that you place throughout your home as needed, or you can opt for a whole-home filtration system that works with your existing HVAC to clean air as it is pumped into your living spaces. You’ll find that these systems differ greatly in terms of cost, convenience, and effectiveness, all of which you’ll want to consider before you make a decision about the product that’s right for your home.

You should also know that different products may have different uses. Yes, they all help to improve your interior air quality, but some are designed specifically to deal with health issues related to indoor pollutants. If you suffer from asthma, allergies, or other respiratory disorders, you might want a more powerful air filtration system to help combat your condition. In this case, you should probably pay attention to two things: the type of filter and the CADR.

There are all kinds of filters to choose from, but if you’re looking to target a wide range of pollutants, a HEPA filter can likely serve you best. This type of filter can trap allergens as small as 0.3 microns in size, which means particulates like dust, dander, pollen, mold, and even bacteria will be caught by your filtration system. Some harmful particulates like chemicals and smoke may require an ionizer to get rid of, but a HEPA filter can deal with many of the allergens that commonly pollute interior air.

You’ll also want to pay attention to the CADR, or clean air delivery rate. This number can tell you how efficient an air purification unit is based on the volume of air it can divest of certain particulates within a given time frame. When it comes to¬†indoor air pollution, you needn’t continue to suffer. Although some measure of common particulates in your air is inevitable, you’ll want to do everything you can to make your interior air clean and breathable, especially if you have respiratory conditions. And the proper air filtration system can significantly improve your indoor air quality.
