An air purifier is only as good as the filter it uses, and that filter has to be changed. This is a must have for continued maintenance on your air cleaner, pricey but necessary.

4 filters for around $25. That is a year’s worth of pre-filters. You need to change these out every 90 days, but you change the Hepa filter out once a year.

Good price with free shipping and no tax at Amazon.

I was pleased with how quick the order came with costing extra. The package was well wrapped. I will be ordering again.

This is a box of four filters that go into the Whirlpool Whispure 510 air cleaner I have. An indicator on the machine shows when the filter inside is too dirty for effective cleaning. I have vacuumed an old dirty filter about twice and reused it with no ill effects that I can detect. But finally I needed new filters. Amazon’s price was best when I checked online.

These are excellent pre-filters for your whirlpool air cleaner. This was the first time that I purchased them from Amazon.com and I wish I would have visited this site much sooner. The price is great!
