280mm x 140mm Computer Case Fan Dust Filter PC Mesh Filter Cover Grills with Magnetic Frame, Black Color (2 Pcs)

Good, fit, easy, and simply works. Will not filter all the dust, and will reduce the airflow, but it works to its expectation. Would be nicer if using a stronger magnet.

Size was correct and as stated. Built nice. They were easy to apply. Just slap on and they are ready. They help with the dust but wont eliminate it. There are some dust particles that make it through and can we seen when removed. That is the nature of small particles and expected. I wish the magnets were a bit stronger. Does the job as need though. They look sleek on the top and side panels. Avoid cleaning with wet wipes as they will snag the fibers.

great and if I got the right size would've been perfect lol but that's on me I ordered the wrong size BUT these do exactly what they're supposed to do they work great

I've used dust filters like this on PCs for years. If you have cats, they're a must-have over any fan intakes.My current computers have integrated filters, but I bought these to cover a couple of metal floor vents/registers in my home. These affordable, sturdy, well-made dust filters allow hot or cold air through, but minimize dust, while simultaneously preventing debris from falling into the ducts. The magnets allow these filters to stick to the metal registers, while remaining easily removable for cleaning.I use one to minimize dust in my home office, and another to protect a vent near our cat's litter box, to keep out any tracked litter debris. This product is more economical, and environmentally friendly, than the disposable fabric filters I was previously using.While I bought these for a different purpose, I would not hesitate to use this product if I purchased a computer without built-in filters.

Both arrived with a slight bend in mesh on top right corner but they still seal around the magnets.

Love these things. Have them covering every single grate on my PC case! really helps stop alot of dust from making its way into my PC which makes cleaning easier.

The top of my 10 year-old Corsair mid-tower 330R case has no dust screen. I probably should have ordered mesh and self-adhesive magnetic strip to make my own that fits, but I went the lazier route; these are a pair of pre-made screens that are nicely finished and fit almost well, covering a size commensurate with a 280 mm opening (the size of a pair of 140 mm fans side by side). This approximates the size of the top opening, is just a bit shy of all the holes. It was a quick-fix compromise. I'll be replacing the case in the future when I upgrade to one of the monster sized graphics cards, but this is a decent and economic short-term solution to keep the internal dust accumulation down. (Note: bigger holes exist elsewhere in the case, like the majority of the case back, but I mostly keep a slight positive pressure interior during operation [I think].) My new build gets the top off due to my temporary cooling solution needing a top mounted radiator. I'll soon be going back to the Noctua NH-D14 I was formerly using as soon as the AM5 adapter I ordered arrives. Then the top goes back to being covered (it's a 'quiet,' noise dampened case). I know, TMI; but someone may appreciate the extra detail and I enjoy writing it.

I needed some cheap covers to keep debris from entering unused fan holes and this magnetic option worked perfectly.
