Pros

•Works effectively to eliminate bad smells, cooking fumes, and pet odors, making indoor air much fresher
•Nearly silent operation, especially at night, ideal for bedrooms and quiet spaces

•Suitable for large spaces up to 1400 sq ft, perfect for wholouse purification

•Improves allergy symptoms and reduces dust, pollen, and pet dander buildup
•Easy setup and reliable performance, with a clear display for monitoring air quality levels
•Great for pet owners, reducing pet odors and maintaining a fresh environment
•Effectively tackles cigarette and marijuana smoke odors within an hour

Cons

•Particle indicator often stays at maximum, which may overstate actual air pollution levels
•Odor Neutralizer Technology can produce a scent that some find unpleasant or ineffective
•Display sometimes defaults to flashing orange and fan speeds change unpredictably
•No remote control included, which could impact ease of use for some users
•Some reviews question the need for cleaning the permanent filters if no visible dust appears after weeks
•Performance on actively improving air quality can be inconsistent, leading some users to plan returns or further testing
•Faster fan speeds during cooking can be louder than desired, especially at higher settings

Bottom Line

We think the Shark NeverChange Air Purifier Max offers excellent odor and allergen control, especially for pet owners and those with allergy concerns. Its low maintenance with 5-year filters and large coverage make it a good choice, though some users find the air quality sensors and odor neutralizer to be inconsistent. If noise level flexibility and a more intuitive control experience matter to you, you might want to explore other models with remote controls or more stable sensors.
