<h1>Get the Right Pre-Filters for Your Air Purifier for Best Results–Especially for Smoky Rooms.</h1>

Replacing prefilters in your air purifier is an important step to make sure you get the maximum life out of your HEPA and carbon filters, but making sure you buy the right type of air purifier prefilter is important, as well—especially for smoky environments, rooms, etc.

 

Air purifier prefilters have one main function: to remove larger particles and substances that would clog up a HEPA or carbon block filter prematurely, resulting in costly 3 month main filter changes. And in most cases, changing the prefilters every 3 months is adequate. For smoky environments, however, not only is it recommended to that you replace prefilters every 1.5-2 months, but also that you use the correct type of prefilter. Prefilters for smoky environments need a tar-trapping substance blended in with the filter material to stop ‘globules’ of tar from slipping through and staining your HEPA filter, and clogging both the HEPA and carbon filter.

 

A lot of air purifier pre-filter manufacturers recommend or offer a carbon prefilter made of a black foam-like material, stating that it will help with odors. First of all, there isn’t enough carbon to really have any odor-reducing effect, and second, that does not trap the troublesome tar mentioned above. And if your air cleaner is designed or smoky environments, the prefilters should be of the proper ‘tar-trapping’ type—if not, perhaps that air cleaner isn’t as good of a deal as you thought, because without this type of prefilter, you will be spending quite a bit on replacement HEPA and / or carbon block filters.

 

There is one other possible solution, however, if the prefilters are the only problem: find some aftermarket prefilter material and cut to fit. Prefilter material is the only situation where you can sometimes get away with using aftermarket or non-manufacturer filters. The HEPA and carbon filters have to fit very well to prevent leakage and that requires that they be proper prefilters, from the manufacturer for best fit. For prefilters, however, a ‘good’ fit is good enough, and it’s often much cheaper to ‘roll your own’ for prefilters, as long as you get the right type for a given situation. If your air purifier comes with a prefilter, we do, however, recommend that you buy manufacturer-made replacement prefilters for best fit and performance, unless it doesn’t trap tar and you need that for your situation.
