<h1>Air Purifier Pre-Filters: The Secret to Saving Money on Replacement HEPA & Carbon Filters</h1>

Many air purifiers come with some kind of pre-filter to remove the larger particles so they don’t prematurely clog up the more expensive HEPA and carbon filters. And these prefilters work well to preserve those main filters, as long as you replace them every 2-4 months or at least vacuum them if they are the type that can be vacuumed without damage. Many air purifiers, however, don’t come with a pre-filter, stating that their systems are so efficient that it doesn’t need one or they just don’t talk about it—and those are the air purifier manufacturers that typically recommend buying replacement HEPA and carbon filters every 6 months. Hmmm….wonder why that is?

 

Truth is, if there isn’t some kind of pre-filter that stops the larger particles before reaching the HEPA and carbon filters, it is going to clog them up. Period. And if you don’t replace the pre-filters regularly, what happens is those particles build up in the pre-filter, restricting air flow, then some of the particles start pushing through, which means they’re going to clog up your main filters pretty soon. And, since airflow has been reduced, the air isn’t getting cleaned as well or as quickly, and that means you’ll be breathing dirty air more often, with more allergies, asthma attacks, etc. Wonder why your allergies have come back?  You might just need to replace or install pre-filters, not get a new air purifier or buy a whole new set of filters.

 

Ok, so what should you do? If the air purifier has pre-filters that aren’t cleanable (electrostatic type, such as Aller Air / Electrocorp), buy some pre-filters when you buy the unit or often enough to replace them every 2-4 months. If your air purifier doesn’t have a pre-filter, buy some cut-to-fit pre-filter material and place in front of your other filters, so that the air goes through the pre-filter first, and then replace that every 2-4 months. Pre-filters are relatively inexpensive when compared to having to replace HEPA and carbon filters,so it just makes good sense to buy and use them regularly if they’re going to extend the life of more expensive HEPA and carbon filters. How much of a difference can HEPA and carbon prefilters make? How about almost 3 x the life compared to not having a pre-filter? That can save you a lot of time and money—or you can not use prefilters and spend 3 times as much on filters per year—which I don’t think anyone wants to do.
