Very hard to find to 1990 unit. Excellent service and delivery. Unfortunately, the actual unit died 15 years ago, but I still need the filter.

Exactly what we needed
We measured our old prefilter that had developed a frayed edge and checked the model number, but couldn't find it at any of the boxstore sellers like that one that starts with A. Decided to order directly from this Honeywell site. Price was reasonable, delivery was relatively quick and the prefilters fit perfectly. They are doing the job and we are happy with this purchase.

Replacement filters for Honeywell Air Cleaner
I'm very pleased that Honeywell has replacement metal filters for a 30 yo electrostatic air purifier. The filters are fragile and break easily but when intact work well. I appreciate Honeywell's support for such a dated system that is still effective.

One of two filters in the original order is defective that happens sometimes BUT replaced professionally and courteously ... which I very much appreciate.

I was very impressed that Honeywell had the exact 4 prefilters aluminum grates for a nearly 30 year old Air Cleaner. They were easy to order and arrived promptly.
