This review is from: Whirlpool 8171434K Large Air Purifier Carbon Pre-Filters, 4-Pack
We have had our Whirlpool 450 air purifier for a little more than 2 years, and find that these pre-filters last 3+ months as advertised.
We have also tried a "generic" replacement pre-filter, which worked fine. After switching back to these (as there was not much savings with the other, and they're not offered on Amazon), I realized that these Whirlpool filters have nice little "slits" that help them attach in the right spot inside the air purifier. (That being said, the slits also make it such that there is a definite "up" or "down" to the filters.)
This package of pre-filters arrived in a tidy box (convenient for storage). I'm sure we'll be back for more, as its tough to beat the price and quick shipping.

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!

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.
