Best air purifier deals: Save big on Dyson, Shark, TCL, more

Small, manageable, freestanding, and ready to clean, this air purifier operates at a minimal noise — of 22 decibels — and cleans up to 215 square feet of space. Enjoy cleaner, more fragrant air via HEPA filtration, which removes 99.97% of contaminants and particles. Each unit comes equipped with a 2000-hour capacity cartridge, with a red indicator light that tells you precisely when it’s time to swap out the filters and cartridge. It’s recommended to change the cartridge every 3 to 6 months.

This medium-sized air purifier is meant to sit on a table, counter, desk, or surface but still offers coverage for up to 400 square feet. The lowest and quietest setting only outputs noise at an estimated 25 decibels. The air passes through a 3-stage HEPA filtration system to remove contaminants, particles, and odors. There are three fan speeds, easy-touch controls, an aromatherapy function, multiple cleaning levels, and much more.

Morento H13 True HEPA Home Air Purifier — $90, was $200

This large and freestanding unit filters up to 1,076 square feet of space while displaying the current air quality on the included display. True HEPA filtration removes 99.97% of microscopic particles, including pet hair, pet dander, dust, and more. The double-sided air inlet ensures that it’s extremely effective, especially in an office or bedroom. You get three timer settings, four fan speeds, and automatic modes and scheduling to offer more intuitive options.

Shark Air Purifier 4 — $211, was $350

Sleek, sexy, and modern all describe the aesthetics of this air purifier that will blend nicely with your home decor. But more importantly, it’s capable of servicing up to 1,000 square feet with its 4-fan airflow, ultra-fast, and ultra-quiet fans. Using Clean Sense IQ technology automatically measures air quality and adjusts its operation to match — constantly cleaning when necessary. An anti-allergen HEPA filter removes up to 99.98% of large, small, and micro-sized particles, with heightened odor protection to remove strong and strange odors. A remote is included so you can control the unit from afar, like when you’re relaxing on the couch or lying in bed.

Versatile is the keyword here. It quickly cleans up to 635 square feet in about 12.5 minutes but can also clean up to 1,524 square feet in 30 minutes on the high setting. In other words, it can clean small, medium, and large-sized rooms given enough time. Above all, it does all of that quieter than comparable air purifiers, which means you can rely on this system day or night. HEPA filtration captures 99.97% of particles, with smart functionality to monitor, configure, and put you behind the cleaning controls. An intuitive LED display built into the unit tells you everything you need to know, even if you don’t have a phone or don’t want to connect one.

The Dyson Hot+Cool HP07 is exactly what it sounds like an air purifier and fan combo. It uses the same technology that the TP07 uses to capture and filter debris from your air. It’s shorter than the TP07 but can still cover the same square footage. The fan blows out hot air, so you don’t have to decide between keeping warm and clean. You can set it to various different cycles, for instance, a quiet mode while you’re sleeping and a maximum mode when you’re out during the day.

You have likely heard of HEPA high-efficiency particulate air filters. A majority of air purifiers have HEPA-standard filtering. Some vacuums feature HEPA air filtering as well. These mechanical air filters force air through a very fine mesh fabric to trap impurities that get mixed in the air. To qualify as a HEPA filter, it must remove up to 99.97% of particles as little as 0.3 microns from the air. The great thing about HEPA filters is they become more efficient as the air gets dirtier, whereas electrostatically charged air filters require more frequent replacements.

PECO, or photoelectrochemical oxidation technology, on the other hand, is a kind of filter that does not give allergens, bacteria, or viruses any chance to thrive. Instead of catching these toxins, PECO utilizes light to spark a nano-coated filter and achieve a catalytic oxidation reaction. Basically, organic substances are broken down into tiny, harmless molecules. Since PECO filters don’t collect particles, they can clear pollutants about 1,000 times smaller than HEPA filters. PECO filtering purifies and disinfects the air without you having to dispose of anything.

There are many factors to consider when choosing an air purifier. Apart from the brand, start with the size of the room where you will use the device. You may spot some models with the AHAM Verified seal. That sale means the purifier has been independently tested and passed the quality imposed by the Association of Home Appliance Manufacturers. You can also compare the CADR (clean air delivery rate), which refers to the volume of clean air an air purifier can produce at the highest speed setting in relation to the room’s cubic footage. The higher the CADR, the faster and more efficient the air purifier is.
