superb service by richenberg (Eugene OR US)

The prefilter I ordered arrived promptly but in damaged condition via UPS. Clearly it was damaged in shipping. One phone call to On-Time-Direct later and I had a new prefilter on the way and UPS had a scheduled return pickup. No hassle, no extra costs, couldn't have been taken care of more cleanly quickly or easily. The replacement arrived and fits and works well. I can't recommend this business enough!

Reviving an air filter by Steven Cook (Vineland NJ US)

The filter set was original equipment exactly as I was trying to replace. My aircleaner is old, and without the parts I was able to purchase from On Time Direct it would have needed to be placed. I am pleased to have found the replacement filters and electrostatic cells.

On Time Direct by Tom (Harwood MD US)

RE: "Honeywell 203372 Prefilter 12.5 x 19.75". The product arrived later than projected, but that was the fault of UPS and not On Time Direct. The product explanation said there meta frame was stronger than the Original Manufacture. but it is not any different. The Prefilter was easy to install and over all I am satisfied with the replacement product.

Came On Time by Natasha von Rathjen (Pomona CA UG)

This was the first time I have dealt with this company. I received my furnace filters on time and packaged well. My filters are permanent, in that they are hosed off once per month. The filters I had were a bit beat up, so I thought I should order new ones. It was easy to order on this website.

prefilters by Steven J Salta (Lake Oswego Or US)

The order was filled promptly, and the filters were exact. What was crazy was the filters were packaged in a box with bubble wrap big enough to send 30 filters or more. A huge waste of resources for what was sent. Get the appropriate size packaging.

Review by Steve Coraggio (Parlin Ne US)

I called to order "203372" Prefilter screen size 12.5x19.75 from Honeywell. The parts were and shipped received in one week of placing order. They are exactly what I needed and a value for the price. They work extremely well and I'm glad to see that these parts are still available through Honeywell. Also when I initially called to place my order, due to the time difference I did recieve a call back from a customer service representative who placed my order. Later that day, I receieved a second call from a another customer service representative who asked if my order had been taken. I told that rep my order was filled earlier that day.

203372 Prefilter 12.5 x 19.75" by ( )

This aluminum mesh filter is positioned in the air stream in front of the electronic air cleaner, and gradually crumbles over time, especially in salt air environments. The replacement ordered from Honeywell arrived promptly, well packed against shipping damage, and fit perfectly.

Prefilter by Paul ( )

I bought two of these filters to replace the original ones that were approximately 20 years old. I noticed the new version includes a small expansion bracket/clip on the top that provides a fit that's more snug than the older version, and that doesn't impede removal. 5 stars for performance and durability, but I give it 4 stars overall because the pricing ($30+/each as I recall) seems a little high.

Prefilter by Bob Coffey (Loveland CO US)

The new Honeywell replacement filter, part #203372 Prefilter, is approx. 1/8" shorter than the original part, but the pressure clips on the top end allow the filter to fit firmly in front of the electronic air cleaner.
