<h1>Replacement Pre-Filters: How to Extend the Life of HEPA & Carbon Filters</h1>

Many of the best air purifiers and filtration systems have quality HEPA and carbon filters that are sometimes a little costly to replace. And some of these air purifiers also have a pre-filter system that goes before the HEPA and carbon filters, some don’t. It’s been shown in recent studies that those with pre-filters tend to have longer HEPA and carbon filter life. And this just makes sense, really–if you use a pre-filter that removes the larger particles and doesn’t allow the HEPA and carbon filters to become prematurely clogged, you would get longer life from the main filters.

 

It’s important, however, to replace those pre-filters regularly, which are usually much cheaper to replace anyway. Pre-filters do fill up and if left in the air purifier, tend to restrict airflow and sometimes begin allowing the larger particles to get through, which defeats the purpose of the pre-filter. Reduced airflow prevents the air purifier from cleaning the air properly and makes the air cleaner work harder, increasing wear and tear on the unit. So, to really get the maximum life from your HEPA and carbon filters, be sure to replace those pre-filters on schedule (usually every 2-3 months) or sooner.

 

And if your air purifier did not come with a proper HEPA pre-filter system, you can buy some cut-to-fit pre-filter material and place this in front of the other filters so that the air goes through the pre-filter first. This will help you get at least another 15-20% longer life from those filters, which can really save you some money in the coming year. We’re not exactly sure why some quality air purifier brands don’t include pre-filters, but we do know that you can increase HEPA and carbon filter life by using one. At the same time, if your air purifier does come with pre-filters, make sure you replace them with those from the same manufacturer as many of them are specially designed and perform as a system in your air purifier ; using aftermarket cut to fit pre-filter material may not work as well.
