prefilter by patricia bonaquist (hubbard oh US)

Excellent product that fit my furnace like a glove. Cost a little high but no problem. Question why not make disposable prefilters for the air filter??

Prefilter by Thomas D Gensler (Omaha NE US)

Service and availability are most appreciated. The spring loading to permit fitting more variably-sized units starts with the frame too short by about 1/4". Consequently, the fit is very loose.

Just What I Wanted by William Allan Royce (McLean Vi US)

I was very pleased to be able to replace the two prefilters for my over-25-year-old Honeywell Electrostatic Whole-House Air Cleaner. The original filters were in really bad shape; literally falling apart. Epoxy glue no longer held them together. The replacement filters were just like the originals and they fit perfectly into the unit.

Exemplary Customer Service by Marit Legler (Corvallis OR US)

I had included a comment with my online order wondering if the pre and post filters would fit my Electronic Air Filter. I received a call from customer service about 10 minutes after I submitted the order online! They had read my comment and provided the additional information I needed. I am very impressed with Honeywell Parts customer service team! The filters worked out great.

Prefilter for gas furnace by g graham (freeland wa US)

Excellent service from your on-line chat representative! I was at a loss in finding replacement filters that had been erroneously thrown away vs. being washed. Your on-line service directed me to a hyperlink and I ordered my filters with ease. Even though this is an older furnace, they fit perfectly and installed nicely. They filters themselves were of sturdy construction. I have no doubt they will last for years with proper maintenance. Although they seemed a little pricey as I had not been the person ordering them in the past, it is evident there has been no reduction in quality and the cost is justified. Shipment was received in a timely manner and directions to track the progress of the shipment were precise and user friendly.

Honeywell Air Cleaner Filters by Patricia Walsh (East Troy WI US)

We have our original oil furnace and finally were able to find the filters for our Honeywell air cleaner that was installed in 1990. Looked all over for correct size and couldn't so went on line, called Honeywell directly and found the correct filters. They were a bit pricey (hence 4 star rating), but the last ones lasted 22 years (can be cleaned each season in dishwasher) so hopefully these will last as long which will compensate extra cost. Honeywell representative I spoke with was extremely helpful and knew exactly what I needed and very efficient in providing the information for ordering filters. The Honeywell product has served us well over the years and now we know where to find replacement filters also.

Thank you for being so prompt with the filters. They are in and the air cleaner is working. The filters do not look like the old ones (not as sturdy) but I assume they change as time goes by.

Prefilters by Roland Otis (Gig Harbor WA US)

I know our model is old (25 yrs) but I want to say that your rep. Josh, gave me a lot of good info. When we had our electric filter installed we were told to put it in the dish washer and not use any dish soap. We used the dish washer and cleaned the unit and prefilter. The prefilters ware frayed on the ends so we wanted new ones. Josh told me to soak the unit and prefilters in dish soap (Cascade granules). Who would have known. I have not washed the electric filter as yet. The prefilters do not need washing. Again I want to thank Josh for the good tips.
