Honeywell new post filters by Dan Linscheid (Salem Or US)

I have been encountering problems with high voltage arcing from the ionic wires to surrounding metal on my Honeywell electronic air filtration system lately. I tried cleaning the wires with fine grit sandpaper, but the arcing soon returned. When I replaced the existing activated charcoal filters with the newer type post filters the problem went away immediately and has not returned.

Gotta Love Honeywell by ( )

We are exceptionally satisfied with our Honeywell Air Filtration System. What makes a superior product even more superior? Customer Support, be it technical assistance or parts. Honeywell is 5-STAR in both categories.

What the Doctor Ordered by Eric Lick (Gig Harbor Wa US)

We have had a Honeywell Unit for several years. The ability to promptly access Honeywell and secure the needed replacement parts makes our patronage of Honeywell and all of its products that much more likely. Special Thank You to the Service Representative who assisted with this order. I apologize I forgot to record his/her name. But we would appreciate your researching this and providing some form of recognition for a "5 Stars" encounter.

Good fit so far by ( )

I added these post filters to a unit that originally did not come with a set of post filters. These were not made to go into my unit, but did so with just a tiny bit of wiggling back and forth. I hope they work to collect some more media from our household air, will not know how well they perform until the first cleanout in about two weeks. I havent noticed a major difference when I dust the house so optimism is a little low right now. Otherwise, happy with the product

works well; seems a bit pricy by Richard Huffman (Mountlake Terrace WA US)

This works well; basically allowing me to have the pre filter, the actual electronic cleaner, and now this post filter on my heating system. My biggest worry is that there would now be too many things impeding air flow, making the whole system inefficient. But I haven't noticed this much so far; it feels a teensy bit like the system isn't delivering the same airflow as before, but it's not a huge difference. The price feels way too much though... But for someone who has massive allergies like me, it's worth it to have another tool in my arsenel for eliminating ambient dust...
