Whirlpool 8171434K great air purifier carbon pre-filter, 4-Pack 
Pre filters are good for your whirlpool air cleaner. E 'was the first time that I bought from Amazon. com and I have visited this site much earlier. The price is great!

This is a box of four filters that go into the vortex Whispure 510 air filter I have. An indicator on the machine indicates when the filter is too dirty inside for cleaning. I sucked an old dirty filter about two times and reused without any side effects that I can detect. But in the end I needed new filters. Amazon's price was better when I checked online.

4 filters for about $ 25. Worth a year of pre-filters. You must change these every 90 days, but you change the HEPA filter once a price an.Bon with free shipping and no tax on Amazon.
