The Shark NeverChange air purifier is already affordable, but this 40 percent discount makes it an even better deal. Like other models in Shark’s NeverChange line, this model boasts a five-year filter lifespan when used and cleaned as recommended, potentially saving hundreds of dollars on replacement filters.

Shark has a few other WIRED-tested models on sale, which I’ve listed below.

NeverChange Air Purifier

The Shark NeverChange Air Purifier exchanges the air nearly five times per hour in spaces up to 130 square feet, making it a good fit for small rooms such as bedrooms, bathrooms, and laundry rooms. It has a long-lasting HEPA filter that captures fine particles, and an activated carbon filter that traps odors and gases. As mentioned above, one standout feature of this budget-friendly purifier is its filter, which can last up to five years with regular cleaning and use on energy-saving settings. It’s also a good option for pet owners: There’s a small cartridge filled with a fragrance pod to help offset pet odors and keep the air smelling fresh. This makes it ideal for rooms where you store your cat’s litter box or have your dog’s crate.

If you want a compact air purifier that’s ideal for smaller rooms, can operate close to a wall, and uses useful odor-neutralizing technology, the Shark NeverChange Air Purifier is a solid choice. At nearly $100 off, this discounted model is ideal for pet parents looking to fight odors and dander.
