Westinghouse Air Purifier True HEPA Filter Replacement Compatible with 1804 Model (Set of 4)

Excellent quality and functionality. Seems like it will last for a long time. Very versatile compared with all other stands I've purchased.

I bought a Westinghouse air purifier and was pleased that the replacement came with 4 in the packaging. It was very easy to exchange out as well.

OEM, fits as expected

I bought the replacement filters for our portable HEP air purifier. My grandson is visiting and he is asthmatic so we set it up in his bedroom. I haven't had to replace the original filter that came with the purifier yet, but I wanted to have replacement filters on hand.

Works long time! Before change even out camping! Works better then those big ones!

I live in California and for some reason, the machine these work with is not allowed to ship here. They are pricey for what they are and you could technically cut material from a bigger filter and make this yourself but it wouldn’t be pretty. I was able to find frame pieces that these filters sit perfectly in and was able to DIY a cooling fan. I simply put it together with extra frame pieces, strong computer fans and a cheap mini humidifier. If the price drops, I’d stock up on these because they do work as intended and now that I’ve built something myself that fits this, it makes life easier. Still hoping that I’ll be able to purchase the machine at some point too. These trap a lot of stuff. California air is kinda bad right now with hundreds of fires around us and I can see that the filters have a thick layer of ash and other crud on them. The inside is still perfectly clean. Nothing visible gets through.

Noticed my air purifier from Westinghouse has been keeping the air in my apartment fresh. I smoke sonI can really tell the difference. Will purchase another purifier again from Westinghouse ❣

Very easy to install. Superb feeling of freshness in near total silence!

Fits properly and works well!

A great portable filter to keep lungs free from all the nastiness out there. I take it to all of my appointments and even on a plane-which was just what I needed! I highly recommend not only the portable filter but of course the filters that go with it!

I received exactly what I ordered on time and well-packaged.

My 1804 had a defective battery, and Westinghouse customer service is non-existent. I wasted money buying extra filters on top of the money I wasted on the device, and also the time I wasted attempting to get service (within a few months, well within the sensible period for defects).

Exactly what I ordered and it arrived ahead of time. Easy to install these replacement filters.
