Air Purifier 4 (HE402)

I bought one. Not so sure it works. The light ring that indicates a change in air quality does change when I cook. I’m in an apartment. The unit is in my living room. But it takes a good 40 min to an hour to get back to 100 %. I would think that’s just the natural time of the air clearing. No help from the unit. 🤷🏻‍♀️ Also I just put it in the bathroom w my bf while he poops. No change in the air reading or smell of the bathroom. After this test I am returning.

I have two Shark ones too, I'm happy with them. One is also near my cat's litter box, mainly because I'm super paranoid about my house smelling for guests. I've visited too many homes over the years that look clean, but are definitely smelly. I know when you're the one living there, you don't even notice it. Just a recommendation as a fellow cat owner though, I switched to pine pellets a year and a half ago and there is almost NO smell from the litter box, it really absorbs the urine. Added bonus there's no dust like with clay ones (I don't trust the even the ones that claim they are "dust free". I use this brand: https://www.petco.com/shop/en/petcostore/product/feline-pine-cat-litter?srsltid=AfmBOorIHcL_YhTcQId9bj7qgmBmG-vFBd88---gl8sP_gKCQjoiPhx_ A 40 pound bag lasts me around 3.5 months with one cat.

I think this is the worst it’s been so far. I’ve had my shark air purifier going full blast, windows closed and wearing a mask indoors.

I have the shark air purifier. It’s good for 650sq ft and I found it does a pretty good job. Has automatic fan control for power savings, an air freshener pod system, and some nice digital metrics to tell you what % of your air is clean. They claim a never change filter (I still might change it myself one day). Overall no complaints.

I have one and I love it! I have two sick people in my house with a cold. It’s been kicking on a lot lately because it detects bacteria and viruses in the air. 🦠

I just bought a Shark air purifier and it’s near the kitchen. No more food smells lingering in the kitchen. It does NOT like sauerkraut, burnt eggs or fried tortillas 😆

We bought a big Shark air purifier at costco that seems to do the job pretty. We use one to hand the downstairs living/dining/kitchen area and then another one for our bedroom.

I’ve got a shark one and I’m still not converted if they work .
