One thing I've noticed is that air filtration systems are like printers in that the lifetime ownership expense is mostly in the consumables. Check the price of replacement filters before you commit.

Be very sure that the filter is actually washable. That’s weird. Like washing a regular automotive air filter.

Many aftermarket and performance filters use fabric rather than paper and are washable. I assume these cloth filters when new are probably not as good at filtering, but after they have gotten a bit dirty they should be just as good as any paper filter. Many folks like the K&N oiled filters, but they have consistently show to let a dangerous, for your engine, amounts of particulates through the filter.

The Winix we just got has 3 filters - a washable prefilter, much like a dryer lint filter, a charcoal filter that ?might? be washable, and the pleated Hepa filter that is not washable.

Same as mine. That HEPA filter is expensive.

4 kids and a big poodle and not a rug or carpet in the house. We don’t live in a dusty climate.

I use these for hvac filters. Being limited to 1” thick filters I feel that anything higher is just too restrictive. I use a washable 5$ scotchbrite pre filter. I can go about an entire cooling season on one filter. And they don’t see much use in the winter.

We run two of these. They are very quite on low. I use wa washable window ac prefilter they have the charcoal filters too. I wash the hepa filters every time it tells me to change them. First filter lasted 4 years. We call them the fart detectors. On a real smokey reload they ramp up to high and can be loud. But most of the time they stay on low

You can spend a lot of money on filtration but this seems to work reasonably well for not a huge up front and consumable cost.
