(Last Updated On: December 3, 2018)

Over the years, pollution has changed the quality of the air, filling it with harmful substances. Various companies have created air purifiers to cleanse household air making it free from toxins and second-hand smoke.

Such air purifiers including those with regulated filters consume a lot of energy. This is because of the massive fan which sends enough air through the filters. However, large fans do not always result in efficient air purifiers.

Depending on the size and model of most air purifiers, they use about 30-250 watts per hour. Let us assume you ran your unit uninterrupted for a year, yours is between $39-328 (at a baseline rate of $0.15 per kilowatt hour) in annual power bills.

However, to have a clearer idea of how much electricity do air purifiers use, you can read the remaining paragraphs. We will also know how to conserve such energy and at the same time enjoy its benefits.

How Much Electricity Do Air Purifiers Use?

Let use a product, the Clair-BF2025 air purifier as an example. This brand of air purifier has a fan do not require equal power as HEPA brands. This happens because of the difference in filter types.

The filters of this product ( the Clair-BF2025 ) use positive and negative charges to trap impurities while HEPA filters use screens for the same purpose. These screens have small spaces which need much air to remove contaminants from any room in your home.

This product consumes various amounts of energy at different settings. At high settings, it uses 2.4 watts, while it consumes 1.2 and 1.8 watts at low and medium settings respectively. Such figures result in a yearly cost of $1.57 to $3.15 at a baseline of $0.15 per kilowatt hour. Although such bills can burn a hole in your pocket, the provision of clean air makes you endure the burden.

 

What  Feature Ensures That You Use Less Energy With Air Purifiers?

Before you decide on the type of air purifier you want to buy, ensure it works well with less energy. To know this, you have to look for the Energy Star Label on the product. This label gives us an idea of the Energy Star Rating which many people tend to overlook when buying electronics.

 

 

Why Should You Consider  Energy Star Purifiers?

When you use small air purifiers with Energy Star labels, you can have savings of more than $25 in power bills. Before replacing your unit, you can save more than $215 in such bills. Apart from air purifiers ensure you use products with Energy Star Labels to conserve more energy and save more money.

 

What Else Should You Consider?

Apart from the Energy Star Rating of air purifiers, you have to consider one other feature. If you only consider the Energy label, you might buy a unit which cost you in the long run.

We call this feature the Clean Air Delivery Rate (CADR). This feature gives an idea of how much air the purifier can exchange in an hour within a room. Higher ratings result in better air quality.

The CADR-to-Watt ratio measures the Energy Star performance of air purifiers. This feature allows knowing the speed at which the purifier removes impurities from the air and the energy used during this period. An ideal air purifier has a minimum of 50 CADR for dust.

You should also know that even if the EPA has its ideal CADR-to-Watt ratio, it does not support any particular brand’s claims.

 

 

Conclusion

Purifiers help improve indoor air quality. But to ensure it works correctly and saves you money in bills, you should check its Energy Star Rating. Apart from the Energy Star Rating, you should also check its CADR-to-Watt Ratio which helps you know how fast it cleanses the air quality.
