🔍 Crucial Vacuum Replacement Filter Set for Hoover WindTunnel Air Model UH70400 – HEPA Style & Pre-Filter – (2 Filters Included) Review

Unfortunately the filter I received in the mail is not of good quality, it doesn't even stick together as you can see in the photos. I tried to fix it and used it once to make sure but it kept falling apart :(

Perfect fit for our vacuum cleaner. And man, we had to change the HEPA filter! It makes a huge difference even though the vacuum has never had any trouble sucking. I ordered a second set to have on hand.

Exhaust filter not suitable. Suitable primary filter. I have UH72400, other reviewers didn't match this model either. Many reviewers said their fit. Maybe because they have UH70400? Either way, waste of money and disappointment, now I have to order direct from Hoover.

I almost bought a cheaper item until I noticed it came with BOTH filters, not just the bottom filter. I had to remove the gasket for the bottom one (no big deal) to get it to fit but both work fantastic and the suction is much better than before. (But that's what you get with clean filters). I will be ordering another set to have on hand in the future.

I love the wind tunnel but I've found it "gasps" when I use it. I ran it for a second with no filter and the audio was gone. A sure sign that it's time for a new pair of filters. The washable filter is washable, just make sure it's completely dry before putting it back in! These replacement filters are perfect for my vacuum and I couldn't tell if they were from a third party and not directly from the vacuum. Make no mistake: you are perfect.

Well made, good product. I've read reviews about the HEPA filter not being suitable. However, I have noticed that if you remove the gasket on the filter, it fits just like the original. I assume this part can be used in several different models, some require a gasket and some don't? In this case, I would advise Crucial Vac to include a printed notice of this fact with the product. I bet this will cut into your profits significantly.

Purchased as a set of HEPA Style Filter 303902001 and 1 Main Filter 303903001 for my Hoover WindTunnel Air Model UH70400 Vacuum Cleaner. The primary filter 303903001 works fine but the HEPA filter 303902001 will not fit. Compared to the original HEPA filter, it has a hard spherical part in the middle that doesn't allow you to reattach the filter cover. I don't know if the wrong part was sent or the part was engineered incorrectly. waste of money and time. End up buying a new air purifier.

HEPA filter is the exhaust filter in question. It fits snugly on my 72400 if you remove the rubber grommet. Factory also unsealed if you look. It works well and I don't notice the air moving around the filter (see particles around the edges). The intake filter fits and looks almost exactly like the factory filter. They are good for the price and Crucial has good customer service whenever I need anything. ETA: Having used these filters for a while I would be wary that the main filter doesn't…
