[This review was collected as part of a promotion.] I live in Minnesota and recently the air quality got worse since there are forest fires next to the Canadian border. This Shark Air Purifier unit gives you more than an average home air purifier. It's not just high performance up to 1200 sq ft, smart technology, real HEPA filter and so on. It is a quiet, powerful and well designed unit. I recommend it for every household especially if you are sensitive to the air quality in your living space.

Sat April 04, 2026 initial product review. STRICTLY to inform a one star reviewer of misinformation that the HP305 is Fake because It is NOT a fake: (B®u©€ 03.27.25) (it is too soon to verify how well it preforms so this will need a revision... my first fear is that it will be prior to 5 years that I will need to replace the filter because I have to short hair cats... I'm really thinking within the first 6 months but this is just an assumption for now) The Shark HP305 and HP302 are functionally identical air purifiers within the Shark NeverChange MAX series, with the primary difference being color. Both units feature 5-year HEPA filters, odor neutralization, and Clean Sense IQ technology, delivering similar performance in odor reduction, particle filtration, and coverage.  Key Differences and Similarities: Color Variant: The HP302 is typically white, while the HP305 is black (or a different variant color). Performance: Both models (as part of the HP300 series) deliver the same air cleaning power, designed to cover large rooms up to 1,400 sq. ft. in 12 minutes. Filter Technology: Both utilize the same NeverChange HEPA filtration system, featuring a pre-filter and a 5-year lifespan. Features: Both models include odor neutralizer technology and automatic air quality sensing. Dimensions: Both share the same physical design: ~22.5 inches tall and an 11-inch diameter.  Ultimately, the choice between the Shark HP302 and HP305 comes down to color preference or price, as there are no functional differences between them.

We started noticing a difference in our stuffy sinus relief at about day 2. Would recommend

Great air purifier. I have several of these in two different homes and even ordered for my kids.

Absolutely loving my Shark never change

The sensor reading never changed off of 100. Returned the item.

Noticed a huge difference in pet hair and dander from our 2 Labradors. No more dinner smells lingering! Best part is we just wipe the filter clean!

I have bought a few air purifiers and never noticed a difference with dust and pet dander. This! I had to dust once this week instead of daily!

Like it so far. Seasoned some cast iron in the oven which caused some odors and it showed red and sped up until it showed 100% again.

I just bought it yesterday. For my baby , the air of the Shark neverchange air purifier is very Fesh they have smell very lear , especially we don't need to change the filter until 5 years. I love it so much .
