NispiraOdor Gas Reducing Carbon Pre Filter Compatible with Honeywell Type K HRF-K2. Fits Model HFD120/140, HFD300 Series, HFD310, HFD320, HFD280 and HFD230, 8 Filters

The sheer number of filters, which are functionally comparable to the more expensive Honeywell 'K' pre-filters, make this a great bargain. However, depending on your air purifier model, the trade-offs make them a pain to use. My particular purifier, denoted as compatible, is the correct height, but requires cutting the sides of the filters off. Also, for a good fit, you have to make small notches on the top and bottom. Another minor complaint is that every single filter (or two, I don't remember) is individually wrapped in plastic. I would have preferred a less wasteful strategy. Overall, a good bargain, and much better than the "large particle only" washable pre-filter my unit came with. I'm sure some filters don't require cutting, so your experience might be easier.

The best price I could find for these filters. They are exactly what they say. I run my filter all day and they do need to be checked every week. They sometimes get dirty quickly, but can be washed several times before you really need to replace them. I just wish the company would sell the permanent filter that initially came with the machine. Mine did not have one in the box, and it would have been an expensive hassle to try to return.But I digress. Good value, good fit.

These are much better than the previous brand I purchased. Really traps dust, pet hair and odors.

I felt there was a slight odor to them.

gets rid of odors fast

I was paying anywhere from $19.99 - $24.99 for a box of 2 Honeywell pre carbon filters. This is an awesome deal to get 8 precarbon filters that are compatible with my Honeywell Air Purifer & perform in my opinion the same as the brand name precarbon filters. Will purchase more when I need to replenish my supply.

Fits Honeywell Air Genius 5 perfectly

Excellent most Excellent. And great price.

These are the best of all previous brands that I tried. They are priced reasonably and fit my AirGenius 5 perfectly.

What’s not to like? Works great. Great deal.
