NeverChange Air Purifier, 5-Year Filter Life, 650-sq Ft - Black HP152

https://a.co/d/gvmjZlS I have no complaints. Shark purifier with air quality indicator and fever change filter.

Yeah, Shark is mediocre and uses misleading marketing. Frequent issues with the AQI display as well.

Please read the AutoModerator comment. Air purifiers aren't good at reducing *visible* dust as it's larger and heavier than "invisible" pollutants like PM10 and PM2.5. The same goes for pet hair. Sans is terrible. Shark is mediocre. Avoid both. Coway is generally one of the highest quality consumer-grade brands. Winix is good, more mid-grade. Blueair has an always-on ionizer. Some people want to avoid this because of possible health effects associated with ionizers or changes in gaseous air chemistry. Per the AHAM 2/3 rule, a space 600-800 sq. ft. needs minimum Clean Air Delivery Rates (CADRs) of 400 CFM - 534 CFM. Unfortunately your budget doesn't support a single large or multiple conventional HEPA purifiers. (An example that meets CADRs would be the [Coway Airmega ProX](https://cowaymega.com/products/airmega-prox).) If you still want a conventional HEPA purifier, go with the [Winix C909 at Costco](https://www.costco.com/p/-/winix-c909-4-stage-air-purifier-with-wi-fi-plasmawave-technology/100842491). It's a bit of an energy hog (95 W) and somewhat loud on the highest setting called "Turbo" (60 dBA per the Decibel X Android app), but it's good value for money. The C909 has PlasmaWave, a bipolar ionizer. You may want to keep this off if you have pet birds. Another option may be the [AirFanta 3Pro](https://air-fanta.com/products/airfanta-3pro). It uses Efficient Particulate Air (EPA) E11 filters, which is two filter classes below HEPA H13. Top composite CADR is 413 for the CARB Edition. Price is $159.99. Keep in mind CADRs listed by purifiers apply to the highest airflow speed/setting only. Lower settings have lower CADRs which reduces cleaning effectiveness.

I think I'm parsing your comment here correctly, but... don't buy Shark. It's a lousy brand with very misleading marketing—e.g., "NeverChange" filters. They don't publish Clean Air Delivery Rates (needed to size a purifier for wildfire smoke particulates). It also has a tiny amount of activated carbon so it's useless for VOCs or other gases. We've seen multiple issues with Shark's air quality display malfunctioning on r/AirPurifiers. You need many pounds of activated carbon or other sorbent media for wildfire smoke gases, VOCs, or odors. And even then, plain/non-chemically treated activated carbon doesn't have high removal efficiencies for all gaseous species.

The shark is overpriced and the filter lasts no longer than any other brand (in other words “never change” is a straight up lie). The bad news is that no filter is really going to keep up with a constant dust source without frequent replacement. I’d focus on whichever one has the cheapest filters.

I bought the shark never change as my first purifier just recently and I feel the difference with my allergies. The 5 year filter change really attracted me but after reading here a little more I might need to change it more frequently. I also tried the blue air for my office but didn't like it, I didn't feel any difference and it was noisy, I returned it and got the smaller shark never change .

I use one of the shark neverchange air purifiers. Big fan. It helps my partner, who has severe allergies.

We have 3 Levoit pets, 100% recommend for cat rooms. Hathaspace is good but filters are $$. The Shark Neverchange kicks butt down near the kitchen. Thinking of getting another to replace the Hathaspace. I also have a Pure Enrichment I snagged off Amazon, it's little but mighty. I use it for smoke in the kitchen, in the cricket room, anywhere I need quick clean air.

Shark NeverChange. Ever since I bought it, my bedroom's atmosphere feels lighter and smells amazing.

There's 3 things you can do. 1. Make sure your PC's ventilation system has more intake fans than exhaust and that the intake areas have screen mesh filters over them. This creates an environment that has "positive pressure" which pushes excess air produced by the fans out of any open crevice/vent area. 2. Get a mini ozone generator(like ionic pro turbo or ionic breeze etc). Ozone in extremely small concentrations is NOT dangerous in any way and actually helps keep you healthy by oxidizing microorganisms like bacteria, viruses and fungal spores. Ozone also makes dust "charged" so that it falls to the ground easier and also lands on surfaces for easy capture/cleanup. This leads to the most important step... Step 3. 3. Buy a true HEPA active air filtration device and run it between 40-60% full speed 24/7. A really great HEPA filter is the Shark Neverchange air purifier. If you employ all 3 steps you will drastically minimize air polution/dust which will lead to an almost clean room environment. Though sadly one cannot reach 100% purity, you can bring the dust and pollution down to almost an afterthought lol! I employ all three of these techniques and my room remains extremely clean. Even though dust rarely gets inside my rig, I STILL take my pc apart every 10-14 days for a thorough deep clean with an electric air duster and isopropyl alcohol with paper towels. I really think this is why my rigs rarely ever have any major issues and can last up to 15+ years...

You sound like us when we went shopping for Air Purifiers. It can be overwhelming. We have a single story (2700 sq ft) with 5 humans and 2 large dogs (GSD and Lab). We ended up with Shark Neverchange for kitchen/dining, IQAir for Family/Living Room (2 fireplaces), Blue Air small units for bedrooms, Winix for office, Dyson for Master Bedroom, and Trio for hallway. Got all of them except IQAir from Costco with prices that can’t be beat. Each has its own strengths and weaknesses. What are your priorities? Do you want all the bells and whistles like app control? Feel free to share and will try to share our experience :)

Have a GSD and a Lab/GSD mix so I can feel your pain :). Are you looking to purify just one space in the house or multiple spaces? That should be a factor in your decision. FWIW, we have a Shark NeverChage, a Winix C-610, and an IQAir Atem in our living/kitchen space of about 1400 sq ft. Shark runs 24/7 and sits closer to kitchen. Winix sits next to GSD crate and runs on Turbo mode for 2-3 hours daily. IQAir sits behind the couch, next to other crate, and runs as needed. Those 3 work together to keep our air best and free of pet odors.

I just started havung cat allergies. Would wake up im the morning with my face. completely swollen, lips so swollwn they were cracked and bleeding. My cat does not sleep with me. I got a Shark Neverchange Pet Pro Air Purifier. Also Allergy dry shampoo for the cat. The face swelling improved by 75% in just a few days.
