Envion FS200 Four Seasons 4 in 1 Air Purifier, Heater, Fan & Humidifier
Main features (read more)
The Envion FS200 is one of the machines that you can use to cope with various weather conditions throughout the year. The unit comes with a ceramic heater, which shuts off automatically when tipped over. A built-in true HEPA filter promises to screen out 99.97 percent of the tiny particles in the air.
The device offers three independent settings: a heater alone, a fan humidifier, and a heater humidifier. Some users found a hidden setting, saying that by turning the left knob to humidifier (water drops) and leaving the water tank empty, the humidifier belt will not turn. This gives you a fan-only mode that blows cool air.

1. Dyson Pure Hot+Cool HP04 purifying Heater + Fan: Heater, fan, and purifier
Main features (read more)
With Dyson’s “Air Multiplier” technology, HP04 claims to projects over 77 gallons of purified air per second, so it warms up the room much more quickly. The 350-degree oscillation sends warm air in various directions and helps make the room evenly heated.
HP04 uses a HEPA filtration system to capture 99.97% of microscopic allergens and pollutants as small as 0.3 microns. But HP04 goes an extra mile by combining an activated carbon filter to enhance its purifying function. The model also has a sensor to detect airborne particles automatically and reports air quality in the room through an LCD screen in real-time.
You can control HP04 in multiple ways through a cellphone app, Bluetooth, and Amazon Alexa, in addition to a remote control that can be magnetically attached to the machine.

GreenTech Environmental’s PureHeat 3-1 heater uses photocatalytic oxidation to reverse air pollution in the room. Using ultraviolet light and titanium dioxide, photocatalysis is a chemical reaction that breaks down volatile organic compounds (VOCs), formaldehyde included, into harmless byproducts.
In addition to the air purifying function, the device also works as a humidifier and is suitable for dry months.
