The best air purifier deal is back at Costco.

I have these Winix units all over my house.

Better performing than everything you can find on Amazon and it comes with 2 years of filtration and easy to control on a Wi-Fi app.

AHAM rated for 360 sq ft, but will cover up to nearly 1,800 square feet with one air change per hour.

My favorite feature is the sensors and auto mode. It gives you the ability to set it up and forget about it. The fan speeds will change automatically, the air quality sensor will change colors and let you know it's working and the change filter indicator will let you know when it's time to change the true HEPA filter (I usually set a timer/reminder for my carbon filter change as I do with my furnace filter).

These units have helped my air during wildfires, Covid periods and will be purchasing more as it's cheaper than buying some other units filters.

Anyone else have theirs develop a whine/hum? I had to move it to dog room
Winix includes an extra filter, so you're already at the same price, assuming $80 for Shark + $20 for extra filter.

Shark states 1000sqft of air change per hour, Winix is 1800sqft
Shark is refurb with 90day warranty, Winix is new with (I want to say) 2year warranty, plus Costco satisfaction coverage.

Can't comment on reliability of Shark, but I've got 3 Winix in the house. One of them being maybe 6-7 years old at this point. We use it almost daily.

On the Winix, I did have to open it up and tighten the fan when it started rattling at about 5 year mark. But I think even if someone had to replace it at that point, it would be totally worth it the price paid.
I bought 2 of these units for myself, and my father bought 1 last year. No complaints, have it setup on a schedule and on auto it is nearly silent even when it's only 4ft away from my head. It will ramp-up/down automatically if AQ decreases, and comes with 2-years of filters. Plus, Costco warranty.

If you're looking for one, highly recommended.

Anyone know a reputable PM monitor that doesn't break the bank? Most seem to be cheap/inaccurate Chinese products.

Do you leave them on 24x7? Trying to figure if how much electricity it is using. I have five of these running all day.
They go to auto either overnight (downstairs) or while the kids are at school (upstairs). I am sure our electric bill has increased, but I don't know by how much. I think someone said that the Airmegas are 60W at full speed; I would guess these are about that in Turbo mode, although I run them at high.

Is tightening the fan an easy task or is does it involve digging into the housing and taking lots of things apart?

From what I recall, I just had to take off the front magnetic panel, remove two screws from top and it kinda just opens up. Then tightene the bolt on the fan. I believe it was tightened to left.

Of course, each model will differ. For me it was straight forward.

This is an energy star certified and qualifies for rebates from Local energy companies if they are offering.
Dominion energy in VA offers a $50 rebate. Check in your local electricity provider's rebates portal.
Looks like it's only available from select retailers (costco not being on of them) or via their online portal.

Quote from BradW3135 :
Mine developed a whine after about a year. It's still going after over 3 years but the whine is irratating. Filters are a little expensive so wait to buy then on sale for around. One hepa changed every year and 4 carbon overlays changing every 3 months.
I got two used when my stepson moved across the country and didn't take them with him. I don't know how long he had them, but one has a whine to it that is irritating to me. My wife, however, isn't bothered by it. Like others, I took the thing apart and used sewing machine oil on the moving parts but it still makes the noise.

Got mine's based off of this posting. I'm an extreme allergy sufferer, and I gotta tell you...

THANK YOU.... It doesn't alleviate it 100%, but 80-90%. Clogged nose, head pressure, constant sneezing minimalized (I live in FL, so we get allergens all year round... This yr got me so bad I couldn't see straight at work!).

Left this unit in my bedroom, thinking of bringing my noisy honeywell bedroom unit to my office.

If during the warranty period, they will replace it.
