Shark - 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 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 😆

Clears the air way faster and better than my Dyson. It’s a workhorse.

there are 2 filter, it has pre-filters on the outside that can be washed and inside is a typical air filter cartridge. The idea is the outer pre-filters catch most the debris and can be washed off, saving the inner hepa. But no, it’s not actually never-change, you will eventually have to replace the hepa, I think they say 5 yrs but all depends on

I have this model. It advertises as lasting 5 years between changes, but I think that is inaccurate because each environment is different. I think mine will need yearly or bi-yearly changes.

We've had ours for a few months. We keep it on auto, and don't use the fragrance thing. The purifier kicks on when we are cooking. It's nice and quiet.

I have one and love it. I keep it running constantly. Every now and then it will turn itself off and I have to spray off the filters on the sides and then it goes right back to work. I have 2 dogs and there’s a noticeable improvement in pet smell. I’m not sure where to get replacement air fresheners for it though. I definitely recommend one of these, especially if it’s discounted

Good for cigar smoke.

I’ve been running a Shark air purifier for about 3 months with no noticeable reduction in dust

Just bought the Shark from Costco last night. My anecdotal evidence so far: My college age son has allergies and always wakes up feeling crappy, he said he actually felt good this morning. I let the dogs out this morning and left the patio door open the air quality monitor dropped significantly and the air purifier kicked into high. My husband and I went to bed with sore throats last night after running errands, no sore throats this morning. As someone who is affected the bad air quality I’m getting desperate.

We have 2: one downstairs and one upstairs. They work very well. Only have to change the filters every 5 years.

I bought a shark air purifier a few years ago and it was always at 100% I had to get a replacement and it actually worked.

I have a Shark one in my kitchen and do love it, but only bought it because of our lack of extractor fan and the fact I became a bit intolerant to my cats when I got pregnant. I probably wouldn’t want to spend the money on one unless, like you said, there is a specific issue you need to tackle. A dehumidifier on the other hand - we’ve noticed the air quality rating on the purifier improve drastically since we bought the dehumidifier. The house warms easier and, obviously, there is less moisture and condensation in the house so we worry a lot less about mold and damp in the colder air (especially being close to the coast in the UK).

Mine stopped working after 2 months. Sensors read poor air quality all the time so the unit was running non stop. Luckily I bought it from costco so return was easy.

I have shark, love them!! I smoke weed but honestly don’t smell it when I get home anymore 😜

Shark

Had it for a few months, takes some of the dog smell away… seems to be working well

Buy the shark. The Winix ones die so fast.

I bought ours during Canadian wildfires recently. Have 3 cats. I think it helps, esp with cooking related stuff.

I like my Shark Air Purifier. The filters are reusable and easy to clean, and the unit itself is affordable.

We have a Shark that we got on sale and I like it because it also gives a reading of what the air quality is in the room. But we also have a “levoit” small one from Amazon that we put in a small room, and we’re used the reader on the Shark to see if it works and it works just as well.

There are lots of fraudulent bad air purifiers which are nothing but expensive fans out there. I have asthma, and have 3-4 purifiers of various different stripes throughout my home. Some are indeed better than others. Because i have asthma, I make sure that air purifiers do not have ionizers (which emit ozone and cause respiratory irritation). I use germ guardian, honeywell and shark. Depending on the size of the room, I try to get ones that fit the area in question. The current one I like is: # Honeywell AllergenPlus HEPA Air Purifier, Airborne Allergen Reducer for Large Rooms, Reduces Allergens, Smoke, Wildfire Smoke, Pollen, Pet Dander and More, Black, HPA200

We have a shark that filters very well. I'll hit my bong and watch the air quality go to 0%. That's when I know I'm really getting clean air.

I have had Levoit purifiers and 1 Shark throughout my house, so a total of 9, which range in all sizes. 7 of them have sensors built in, which change the color based on air quality. I also have a couple other sensors one being a Kaiterra Egg the other two being handheld air quality testers from Amazon. I’ve found the readings between them to be very consistent and accurate.

I tried it and returned it. I wanted to use its auto mode. But it doesn't seem to ever turn on by itself. Since that's the primary reason I wanted that model, it just didn't work out.

I suspect that's part of their marketing for the Never Change filter, by using the auto mode.

Don’t get the shark.

Sorry. To expand - don’t get the Shark, it’s poorly built and they’re lying about never changing the filters.

I have a Dyson - it was a gift, and honestly I wouldn’t buy one myself 🤣 I honestly don’t even know if it does anything it’s on in our bedroom. We have two other purifiers one on each floor and they’re sharks, they were about 100$ each. Work great and the one in the basement really keeps the kitty litter smell to 0.
