The rising inflation and cost of living in the country are compelling everyone to think twice before making a decision regarding electricity machines.

I would like to discuss each one in detail so you understand all the information regarding this small and smart machine.

Electricity Consumption

Large Air Purifiers

Let’s keep it simple, the electricity cost depends upon the size of the purifier. If you use a bigger air purifier, you should also know that its large size supports more filters and heavy motors. In short, bigger in size air purifiers consume more energy than small panels. Actually, large motors require more energy than usual to run appropriately, hence, these panels will cost you about 1 to 1.5 dollars per day. Also see How Long Should Air Purifier Run

The consumption of electricity also depends upon the way you use the purifier. If you turn the machine on and forget to shut it down, it will cost you more than traditional purifiers. Plus, some areas are more polluted than usual such as metropolitan cities which are full of toxic gasses and harmful air components. If you live near a road or you have a factory a few meters away, you need to keep the purifier on 24/7.

Small Air Purifying Panels

For such conditions, the cost varies according to size. The bigger purifiers will cost you 1 dollar per day while the smaller ones can charge you $0.24 to $0.40 in case you use them all day. But you should also know that their motors decay with the passage of time, therefore, you will need to replace the panel every one or two years.

How to Lower The Cost

As I have mentioned above, I will tell you how to lower the cost. There are a few tips and instructions one should follow. First never compromise on the quality of the purifier. There are two main disadvantages if you do it, first, the local purifiers emit gasses without filtering the air, and only a small amount of air is filtered. Second, the local purifiers have low-quality and old technology motors for filtering which consume more energy.

Plus, the old technology purifiers do not provide advanced features for example automatic shutdown or smart functions like checking the pollution in the air. However, purchase the latest air purifiers, they are energy efficient. First, they consume less energy about 8.2 to 130 watts, second, they have small and less noisy motors so you can use them without getting irritation.

As well, the average per day cost of an advanced air purifier is about 0.20 dollars to 0.70 dollars. They have sensors to detect pollution in the air. If the air is polluted, they work faster than normal and change the air within minutes. Moreover, once the pollution is eliminated, their automatic smart controller decreases the speed of the motor and the panel stops eating bunches of electricity. Anyway, you should use the latest quality air purifier for lowering the cost.
