Earlier this year, I moved to a new place with windows facing a construction site. To make the air fresher in the room, I bought an air cleaner. And then summer came. I purchased a fan and tried not to rely on air conditioning too often. Just recently, temperatures began to drop, and I was thinking maybe I should buy a space heater for winter time. And I haven’t mentioned that my skin feels dry in winter, so perhaps I need a humidifier.

But the truth is I just don’t have that much space for everything — the air purifier, fan, heater, and so on. So personally I recommend all-in-one machines that I can use all year round. And here are the multi-purpose space heaters that I found, and you may find them useful, too.

What does 2ndactt love about? The space heater comes with a true HEPA filter and helps remove allergens while keeping you warm or cool all year round. With the function of adding moisture in the air, the heater is ideal for dry weather.

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.

  2. Heating element: ceramic 
  3. Dimension: 9 x 10.2 x 25.6 inch

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.
