Key Features of the Envion Four Seasons 4-in-1

1. Air Purifier

So, let’s start with the key functionality, the air purifier. This is a pretty good spec for a combination unit, with a True HEPA filtration system being in place. That means that in air purifier mode it will capture up to 99.97%* of pet dander, mold spores and smoke. It’s capable of capturing allergens and irritants right down to 0.3 microns.

2.  Humidifier

The humidifier function has three different settings, so that’s low, medium & high. When we’re stuck inside and the heating is on, the dry air can play havoc with your skin and result in a dry sore throat, so this is a great solution. The Four Seasons 4-in-1 comes with an empty water sensor which results in an automatic power shut-off for the humidifier.

3.  Fan and Heater

 A powerful, innovative airflow fan instantly cools down an entire room. Over to the ceramic heater, well there is a range of heat settings to give you great control over the room temperature.

4.  Combining Functions

Want the heating on but don’t want the drying effect? No problem, switch on the humidifier at the same time as the heater to create healthy moist heat.


From reading the reviews available on the internet, most users of Levoit Core 300 air purifier seem very happy with their purchase. 

Good value for money.

Quiet when in use and you can feel the air quality improve.

Makes a huge difference to the air quality in my apartment.

Bit of a pain to fill the water tank.

Alternatives to the Envion Four Seasons 4-in-1

Pure Enrichment Pure ZonePure Zone Air Purifier

Although this product looks very sleek, it uses UV light technology to destroy microorganisms.  While it can help how well the system works, I’ve found that this technology can, in some cases, be harmful to the environment. This still looks a very good option though and is worth considering despite being more expensive.

+Energy Star Certified
+HEPA filter
– LED indicator lights are too bright
– Not designed for large spaces

Germ Guardian 4825The Germ Guardian

This air purifier comes very highly rated. In my opinion, however, the product has been let down by its design, which I thought was pretty ugly! The purification specifications of the Germ Guardian are almost exactly that of the Core 300, but this purifier comes in more expensive.

+ 3-step filtration
+ Quiet Operation
– Faint blue UV light keeps shining through
– Doesn’t have many smart features

Rabbit AirThe RabbitAir MinusA2

This air purifier has a 6-stage filtration process that provides the freshest and cleanest air possible. It has a pre-filter, medium filter, HEPA filter, activated carbon filter, customized filter, and an Ion generator. However, it is pretty expensive.

+6 Stage filter & deoderization
+App available for IOS, Android and Alexa
– Only one of the three versions is wifi enabled
– High initial purchase price


If budget is a priority and you’re in the market for several air improvement products, the Envion Four Seasons 4-in1 could be a great choice. Where space is at a premium there are also huge advantages over having one unit to fit in rather than four!

A true HEPA filter makes this a contender if you’re looking for an air purifier to help with allergy problems or simply to enhance the environment in which you live.
