Best air purifier deals
Though this Kenmore Smart 2300e has only a 10% discount, it still deserves a spot on this list as our favorite air purifier for large spaces. It has a three-stage HEPA filter that captures particles down to 0.3 microns, and it's designed for coverage of up to 2,300 square feet. The purifier also allows you to change modes, adjust the fan speeds, check your home's air quality level and more using the companion app.
This Morento dual-air model has been reduced by $10 at Amazon. It has a coverage of 1,290 square feet with Wi-Fi and Alexa compatibility built in. in addition, there are three adjustable fan speeds, low noise of under 23 decibels, voice control and HEPA filters for purifying particles as small as 0.3 microns.
A $200 discount has been applied to this Shark 3-in-1 model that comes with a Pure Air Microforce fan, up to 500 square feet of coverage (based on one air charge per hour) and anti-allergen nanoseal filters. The three modes available are purified air, purified heat and purified fan. The Clean Sense IQ technology tracks air quality and adjusts accordingly.
Discounted by $79 at Best Buy, this Blue Pure 211i Max air purifier is perfect for extra-large bedrooms, offering a range of 3,000 square feet. It's also known for being quiet and having a clean air delivery rate of 410 for fine smoke particles, dust and pollen. While its sister model -- the Blue Pure 311i Max -- is our favorite, this model is better for bigger spaces.
