Honeywell Household Odor & Gas Reducing Pre-Filter, 2 Pack, Black

Great fit, exactly as described and works well.

I got these so I could have more than just one for my purifier. I am glad I did, it is much easier to wash and replace than the current one. Just make sure you cut them down to the right size as they may not fit if you go to small. No complaints here

I've only had this about a week. I have model HFD320. This review only applies to this model. Overall I am happy with this air cleaner and am considering getting a second for the downstairs.My one complaint is the controls on top are so well lit that I can easily see in the bedroom. That hasn't disrupted my sleep, but I wish I could turn them lower. Although the directions specify not to put a blanket over it (who would do that?), it is possible to cut out a black piece of paper to fit over the top at night and secure it with a small piece of tape. This would not obstruct air flow. The top is just controls and indicators, but I haven't bothered.The device itself is silent, but you can hear the air rushing through, but IMO that is not the device though it could be some fan sound. It isn't enough to disturb my sleep when in sleep mode. When oscillating there is no mechanical noise that I can detect.Effectiveness seems good, and turns on a hour or so before bedtime, the air is clearly better than air in the hall. The controls barely require a touch to make changes. I have not had it long enough to see the filter changing light.

Great!

shows what it picks up lots of do hair

Works as expected at a reasonable price

always buy these from here. price is fair.

The filter captures a lot of dust from the room
