If you have a quality portable air cleaner with HEPA and carbon filters, you know it's a pain when it comes time to replace them--mainly because of the cost. And if you have a good air purifier but have to replace filters every 6 months, that’s no fun, for sure. Well, we have some good news--there is a way to extend the life of those main filters--by properly using and replacing pre-filters.
Several good brands of air cleaners such as Aller Air and Austin Air come with pre-filters, and for good reason. HEPA and carbon pre-filters do one main, important thing—they stop larger particles so that these particles don’t’ prematurely clog the more expensive HEPA and carbon filters. They do wear out, however, and need to be replaced because the electrostatic charge is lost over time and they begin to allow those larger particles to get through and shorten the life of your main filters. AllerAir air purifier pre-filters are especially sensitive to vacuuming and you can only do it once or twice before they lose their charge.
Now, if your air cleaner doesn’t have a HEPA and carbon pre-filter, that could be a large part of the reason you have to replace your main filters every six months or so. A quick, easy fix to this is to buy some quality cut-to-fit pre-filter material and cut a piece of it the same size as your first filter and place in front of it. Then, just vacuum it once or twice and replace as needed. You’ll likely notice that you get another 3-4 months or more out of your HEPA and carbon filters! In any case, pre-filters do need to be replaced so vacuum them once or twice but then replace as a rule of thumb. And always use the pre-filters made by the same manufacturer as your air cleaner; they fit better and they’re designed to work with that air purifier, perform better in that filtration system, etc.
