Best Air Washers for Cleaning Indoor Air

While most air washers both filter and moisturize the air at the same time, the BONECO H300 is a step forward from these types of units. It’s a hybrid system that can perform these functions both simultaneously and independently. In other words, you can use it as an air purifier or humidifier only or set it to work as both. Within each setting, you are free to choose between six performance levels ranging from low to high intensity to meet your current needs. Thus, when set to high performance, the unit will cleanse the air and level the humidity up to the norm in less than an hour and low-performance settings are good to maintain the favorable environment afterward at lower energy consumption. With a maximum coverage of up to 540 sq. ft, this air washer is good for mid-size to larger rooms.

In the core of the appliance is a sophisticated filtration system based on high-capacity filters. A pre-filter is meant to stop hair, pets’ fur and bigger household debris floating in the air while the downstream filter captures fine dust, dander, pollen, and other potential allergens including viruses and airborne bacteria. As such, the unit will be of great help for sensitive and allergic users, alleviating the symptoms of allergy and irritations caused by excess air dryness or pollutions.

A built-in air sensor will consistently measure the air humidity in the premises and automatically adjust the evaporation intensity to optimize the water consumption while maintaining a healthy moisture level. And an auto shut-off function is included to turn off the unit when it runs out of water to prevent overheating and system damages.

Many people buy air humidifiers since proper indoor air humidity is essential for health. Yet, only a few think about the air purifier and eventually end up buying yet another unit. The VENTA LW25 air washer is a simple appliance that offers a combo of both functions in a straightforward and no-frills design. “No frills” doesn’t necessarily mean inefficient. In this model, it rather stands for reliable operation free from failures.

To keep the indoor air both clean and moisturized, the VENTA LW25 uses a fairly simple but ingenious system. A hefty fan drags in dry and dirty air that gets directly into the water while two disc stacks rotating in the water reservoir function both as a filter to remove household impurities and as a moisture pad to evaporate the clean moist through the vents on the top of the appliance. Notably, the disc stacks can effectively filter out both larger debris like dust particles and hair and some fine pollutants like pollen, germs, pets’ dander, etc. This system along with cold evaporation technology will let you use ordinary tap water without the risk of the white residue settling on the furniture and other interior items during unit use.

When it comes to the air washer performance, the appliance handles 1.5 gallons of water to cover a room area up to 485 sq. ft, so, whether you put it in a bigger living room or a smaller bedroom, it will maintain a healthy indoor environment equally well. Three power modes allow setting the desired operation intensity to match the room area and the air quality while the humidity monitor will let you see when the healthy humidity level is achieved and you can switch to a lower power mode. Besides, you can choose between an Auto mode (for the day) and a Sleep mode (for the night), in which the appliance will adjust the settings automatically to finetune the operation.

If you are a tech-savvy person who greatly appreciates the convenience of smart devices and uses their smart functions to the fullest, you can’t help but like the smart air purifier from Levoit. A W-Fi enabled device, this model can be easily adjusted and controlled either manually or via your smartphone and can even be integrated into your smart home system via a compatible smart plug.

To access advanced air washer functionality and use your mobile as a remote control, it is enough to download the free Vesync app that will sync with your phone like a charm. Via the app, you’ll be able not only to activate Auto or Sleep modes but also to monitor the current air quality, check for filter replacement, set a timer for the unit to operate within specified time frames, and create complex daily operational schedules for the whole week. To add more, the Levoit purifier can be connected to your voice assistant (Alexa or Google Home Assistant) to give you the convenience of hands-free control.

Coming down to the air washer performance, the device is capable of efficiently cleaning and humidifying the air in an area of up to 322 sq.ft. As such, it’s a better option for smaller and mid-sized closed premises. Besides, with the level of noise at 27 dB in a Sleep mode, it’s a great option for bedrooms and nurseries.

To keep an air washer running, you need to refill the water tank from time to time, which is a normal thing. However, the smaller the tank capacity, the more often you’ll have to add water. And what if you live in a dry region, in harsh weather conditions, or in a more polluted area and need to run the air washer almost constantly? This is where the BONECO W300 air washer will come into play.

What makes this model stand out straight away is the enlarged water reservoir that handles 3.2 gallons of water, which is twice the average volume of other common units. With that, at coverage of up to 540 sq. ft, the appliance can operate up to 3 days before it needs a refill. And it’s worth noting that it will support an optimal air humidity level all this time. If the system runs out of water, a light indicator on the front panel will turn red and the unit will automatically shut off to prevent any damage.

The idea behind this air washer machine is very simple. It blows the air onto the evaporation mat that rotates in water to saturate the air with moisture and filters away some bigger impurities like dust particles and pollen at the same time. Not only is this filtration system more long-lasting but it will also spare you from sticky wide residues on the furniture and electronics usually caused by ultrasonic systems and from too moist air, which is specific for steaming devices. In the meantime, you can choose between two performance modes for day and night accordingly and there is a fragrance container to use the unit with oils as a diffuser and enjoy aromatherapy effects whenever you want.

If you live in a bigger house, condo, or studio apartment with an open-space layout, you will surely appreciate having an air washer capable of covering larger areas and, thus, saving you the need to buy several devices. The HEV685W air washer is just the unit in point. Designed to cover areas up to 1,000 sq.ft., it won’t cost you a fortune at the same time. And the best thing is that it will perform efficiently and deliver its intended functionality to the fullest.

The model uses a wicking filtering system with a fan installed over it. The wicker filter works to trap dust and other common pollutants lingering in the air and saturate the air with moisture. Two dial knobs on the top of the unit will let you set the fan speed and adjust the humidistat. Precisely customizable settings allow for quickly achieving the desired humidity level and maintaining it afterward in an energy-saving manner. This way, you’ll make sure you breathe in cleaner and fresher air when at home and avoid multiple dryness-related issues such as dry skin, nasal congestions, sleeping discomfort, and static electricity.

To cope with larger areas, the Honeywell air washer accommodates two relatively big water tanks to handle 3 gallons of water at once. As a result, the unit is much bulkier than many of its rivals and heavier too. However, the removable tanks with a top filling option make it a real snap to add water when needed. In the meantime, fully filled reservoirs will keep the unit running up to 24 hours at the lowest setting before the next refill, so you won’t have to do it very often.
