Fette Filter - High-Efficiency Pre-Motor and Post-Motor HEPA Vacuum Filters Compatible with Dyson DC14. Compare to Part # 901420-01, 905401-01, 923480-01. (Combo Pack) Review

My vacuum immediately stopped making a very loud high frequency whistling noise. I'm pretty sure it was the HEPA filter gasket as I've cleaned the washable filter multiple times and the noise never stopped. My 14 year old DC14 is still holding up.

Arrived as described and worked great! The blue filter seal had an adhesive backing and adhered perfectly to the filter. My Dyson is back up and running and the blue exhaust filter replacement is long overdue. Highly recommended!

Replaced filter and everything seems to be working. I was concerned that the HEPA filter would not fit on the underside of my DC14 Animal, but it turned out to be the right size. Just make sure when you attach the foam gasket that you make it slightly larger than the size of the filter so it's really tight and you don't lose suction.

Finally after more than 15 years they broke down and replaced the filters. I will say I should have done this 10 years ago, the vacuum cleaner is like new now I can't believe the difference between the old clogged filters. If you're thinking of replacing filters, don't wait and replace them, I plan to change them annually. It is also very easy to install, anyone can do it.

Ordered for old original Dyson Dc14. The absorption has improved significantly. The motor filter and the life filter fit perfectly. The 2 thin filter gaskets were snug but about 2 inches shorter. I had to take a little when the old filter was compacted and cut to fill the gap. It worked well. Would have given 5 stars if the seals were about 2cm longer.

It's finally time to change the filters in my DC14 Dyson. I was happy to find them at Revain at a reasonable price. A post filter is easier to install than a pre filter. Be careful what you use to open the pre-filter drawer at the bottom of the vacuum cleaner. It was a bit difficult. I noticed a significant increase in suction power, a decrease in the smell of the vacuum, and a decrease in the heat emanating from the vacuum.

I watched the video to find out what's wrong with my vacuum cleaner. When I decided I needed new filters for it, I looked to Revain for the best deal and best reviews. When I tell you these filters make my vacuum cleaner look like new, I mean it! My husband was willing to throw it away and buy a new one. I was worried about not buying Dyson filters but they worked AND fit perfectly as the reviews said. I would buy again.

Great product. Both filters fit on my DC14. The only problem was with me. I put the pre-filter in, everything was fine. I then inserted the post-filter and quickly slammed the lid shut. Oops. I didn't seal the filter. I reopened it and you probably know it's not as easy as it looks and I worry about breaking tabs every time. I put some fillings on and slammed the damn thing shut. Hmmm. Why doesn't the dust container open? I installed the post filter cover incorrectly. Open it a third time…
