Good Price
I need to cut an inch off this filter to fit my air purifier, but the price is so low it was worth it.

Very pleased with this filter - it may be BETTER than the Kenmore brand I had been using!
My first order from Crucial Air (along with the HEPA filter also)-Just arrived and installed a few minutes ago.Perfect fit - the slits to align the filter WERE there in my filters, made for easy install.Comparing to the old installed filter (brand name of KENMORE - which was made by Whirlpool and rebranded for Sears) to the Crucial one - the Crucial filter seemed to be noticeably MORE substantial than the Kenmore-branded one.So far so good! Happiness!

Full product description
Four carbon pre-filters for Kenmore large-chassis and Whirlpool Whispure air purifiers. They replace Kenmore 83378 and Whirlpool 8171434 / 8171434K, the same pre-filter under two brands (Whirlpool's older number is 1183063).
What it fits
- Kenmore 295 Series
- Whirlpool AP300, AP350, AP450 and AP510
- Replaces Kenmore 83378, Whirlpool 8171434, 8171434K and 1183063
Also compatible with: Kenmore models 106.4283200, 106.4283202, 106.4283230, 106.83200, 106.83202, 106.83230, 106.83354, 106.83355; Whirlpool models AP35030, AP35030H0, AP45030, AP45030H0, AP45030K, AP45030R0, AP45030S0, AP45030S1, AP51030, AP51030K, AP51030L0, AP51030R0, AP51030S0, AP51030S1, AP51030S2, APR45130L, WP500, AP3003VK, AP4503VK, AP51030H, APR45230L.
When to replace
Kenmore's recommendation is a new carbon pre-filter every 3 months, so a 4-pack covers a year. Don't wash and reuse them.
How it fits together
The pre-filter sits in front of the purifier's main particle filter. The particle filter is a separate part: for Kenmore models, see the 83375/83376 filter, which also fits the Whirlpool AP350, AP450 and AP510 (Whirlpool lists its particle filter as 1183054K).
Larger packs
The same pre-filter is also sold in 1, 4 and 8 packs.
Questions
Do these fit the Whirlpool WP1000 or WPPRO2000?
No. Those purifiers take Whirlpool's extra-large pre-filter, 8171510K.
Can I wash a carbon pre-filter?
No. Kenmore's manual says not to wash or reuse the pre-filter. Swap in a new one.
Is 8171434K the same as Kenmore 83378?
Yes, it's the same large carbon pre-filter. Whirlpool's earlier number for it was 1183063.
