Make your home or office environment cleaner and more comfortable with an air purifier and humidifier in one like the Venta Air Washer. This device will purify the air and also maintain a comfortable level of humidity thanks to its two-gallon water reservoir.

The unit works to purify the air by removing particles up to the size of 0.3 microns. Without filters, this air purifier relies on a wet, rotating disk stack that catches incoming particles. Through the process of cold evaporation, only water evaporates into the air—leaving dust, dirt, dander, pollen and more on the inside of the machine.

It’s recommended that every 10 to 14 days you clean the disk stack and interior housing of the air purifier to keep it running efficiently. There are no filters to purchase for this air purifier, which is a major plus for most users. However, the company does advise the use of an additive that helps to keep mineral deposits from building up and allows the unit to function at peak efficiency by preventing the water from beading up on the disk stacks.

Best High-End: Molekule Air Purifier

Molekule

Molekule 

At first glance, the Molekule might look more like a piece of modern art than an air filter. The sleek aluminum design—complete with a natural leather handle for easy transportation—looks great in any home, but the real draw of this pick lies in its ability to completely replace the air in a 600 square foot room once every hour. The Molekule is an investment to say the least, but you get what you pay for. This unit is incredibly quiet, energy efficient, and easy to control remotely from your smartphone.

One of the major drawbacks of air purifiers is needing to shop for new filters. With Molekule, you can sign up for auto-refills, ensuring that a brand new filter will magically arrive at your home every six months.

Best Quiet: Honeywell True HEPA Allergen Remover

The Honeywell True HEPA Allergen Remover is a popular choice for a quiet air purifier for allergy-sufferers. If you want to enjoy better air quality but don’t want to give up a peaceful environment for it, try this air purifier.

The Honeywell True HEPA Allergen Remover can tackle a room up to 465 square feet in size. It features four air purification modes: germ, general clean, allergen, and turbo. While the lower levels of operation are found to be low decibel and peaceful as background noise, the turbo level is reported to be quite noisy. Still, if you don’t plan to operate the air purifier in turbo mode too often, you’ll find this unit to be quiet enough to fade into the background.

Best for Larger Spaces: Rabbit Air MinusA2

For better air quality in a larger room or open-concept floor plan, choose an air purifier with higher capacity—like the Rabbit Air MinusA2. While many air purifiers require you to purchase multiple units to cover the square footage of your home or force you to move a unit from one space to another, the Rabbit Air MinusA2 can cover rooms up to 815 square feet (or 350 square feet for allergy sufferers requiring a higher air refresh rate).

This air purifier is also unique in that its slim dimensions make it possible to mount it to a wall in your home, saving on floor space. When it comes to making the most of your air quality, the Rabbit Air MinusA2 has a 6-stage process that will leave you with fresher, better air. It begins with a prefilter and medium filter to trap larger particles, then includes a special HEPA filter that has been treated to reduce buildup and increase efficiency.

Next, you can choose from one of four specialty filters to target your specific allergy triggers, such as pets, smoke, or toxins. An activated carbon filter completes the air filtration system, while a negative ion generator can be turned on to add freshness to the circulated air.

People find the Rabbit Air MinusA2 to be a useful way to purify the air and relieve allergies. The customizable filters are also unique and make this a good air purifier for smoke as well. As far as aesthetics go, the minimalistic look allows the unit to blend in, though the blue LED “mood light” can’t be disabled, which might be an annoyance for some people. Overall, the Rabbit Air MinusA2 Purifier is a higher-end choice with a greater capacity for air purification and the ability to clean larger rooms.
