<h1>How to Extend HEPA & Carbon Filter Life--with Pre-Filters</h1>

A lot of people use air cleaners with quality HEPA and carbon filters, and often notice that they’re replacing those HEPA or carbon filters a little more than they’re comfortable with. Of course, if the filter needs replacing it’s because it has become full and has removed a lot of pollutants. And that’s good, right? Sure! But what many people are not aware of is this: if that air purifier does not have a HEPA or carbon prefilter, or a filter that stops the larger 3-10 micron particles before they reach the those main filters, what happens is something called premature filter saturation. That means that the air spaces in the HEPA and carbon filters become prematurely blocked by larger particles, reducing or stopping airflow, and eventually causing the filter to become saturated or full, too soon. And that costs money—unnecessarily.

 

Some air cleaner manufacturers such as Aller Air, Electrocorp or Austin Air include pre-filters with their units because they understand this problem and they want to provide you with an air purifier that offers more value, less maintenance, and better performance. As result, their filters can last on average, 3-5 years. Many other quality air cleaners, such as Blueair however, do not include a prefilter. And as good as Blueair air purifiers are, their filters need replacing every 6-8 months—which is largely due to….premature filter saturation.

 

The solution? If you have an air cleaner with a pre-filter, simply buy replacement carbon prefilters, HEPA pre-filters, or whatever the unit calls for to get the maximum life from the main filters. Aller Air pre-filters do degrade over 4-6 months and can usually only be vacuumed once or twice before they become damaged and start allowing particles to get through. Austin Air pre-filters are made of a similar woven material and need replacing every 6-8 months.

 

If you have a Blueair air cleaner or another brand that does not have a pre-filter, you can still extend the life of the main filters. All you have to do is buy some pre-filter material and cut a sheet that is about the same size as your regular filter and place in front of the main filter set so that this is the first thing the air goes through. You’ll very likely notice that you get anywhere from 40-80% more life from HEPA filters especially, and something similar for carbon filters (depending on use-carbon can become spent faster simply from excess chemicals or smoke in the air). Then just replace those pre-filters about every 3 months and you should be good. That’s an easy way to get much more life from your air purifier filters—and save a lot of money. Doing this, you may get 1-2 years of service—instead of 6-8 months. Big difference.
