Installing air filters in your home is a great way to make sure the air your family breathes every day is safe and free of contaminants. But you shouldn’t just go out and buy the first air filter you see. When it comes to quality air filtration, HEPA filters are the industry leaders, and for good reason. They can remove up to 99.97% of indoor air contaminants that measure 0.3 microns or larger, a phenomenal success rate unmatched by any other filters on the market. Proper HEPA Filter Practices To be effective, even HEPA filters need to be installed and maintained properly. Consulting with an HVAC professional is the best way to ensure that the air filtration system you get is completely compatible with your home heating and cooling system. The filter must also be installed in the appropriate place so it can catch the most contaminants. Especially if you have a forced air heating and cooling system, there are a lot of potential locations for your filters. A good HVAC professional can help you determine which spots will serve you best. Changing Your HEPA Filters Once your filtration system is in place, you should maintain it properly so it continues to catch and remove all those unwanted particles from your indoor air. Keeping up with the proper filter changing schedule is a big part of this. Every HEPA filter comes with manufacturer’s recommendations on how often the filter needs to be changed. Prefilters often need to be changed more often, sometimes even once every 90 days, so you should find out if your system has one of these as well. Many HEPA filters only need to be changed once every year or two, but the conditions in your home can make it necessary to change them more often. For example, if your home has a lot of dust or other specific air contaminants, you may need to change your HEPA filter as often as once a year. Both HEPA filters and prefilters are quite easy to remove and replace. If you’re not sure how to do it, have your technician show you the next time they come out for a routine maintenance visit or when they put install the system. As long as you replace your filters regularly, you should have no trouble maintaining high indoor air quality with a HEPA air filtration system.
