Most air purifiers, specifically those with HEPA filters, consume a lot of power, and with good reason, too. They require the use of a very powerful fan, one strong enough to blow air through a HEPA filter. While more power in the fan may imply a better performing air purifier to some people, this is far from accurate.

Most HEPA purifiers consume around 30-250 watts per hour, depending on the size and model. Hypothetically, if you were to use the purifier for around 24 hours each day for a year, you would be paying around $39 to $328 annually when using a baseline rate of $0.15 per kilowatt hour (kWh).

Clair air purifiers on the other hand does utilize a fan, but one that does not require the same amount of power as HEPA air purifiers because of the filter type. Particles that come close to the filter are trapped using positive and negative charges whereas HEPA filters are just screens with very small spacing between them which require immense air flow to effectively filter out particles in a given area.

Clair-BF2025 Tangerine

The Clair-BF2025 consumes 1.2/1.8/2.4 watts for its low/medium/high settings giving it an annual cost of $1.57 to $3.15 when using a $0.15 per kilowatt hour (kWh) as a baseline.

Clair-TD1866

 

The Clair-TD1866 consumes 2.64/3.96/5.28 watts for its low/medium/high settings giving it an annual cost of $3.46 to $6.93 when using a $0.15 per kilowatt hour (kWh) as a baseline.

Costly energy bills are not something consumers must accept when it comes to air purifiers. Ultimately the most important thing is improving the quality of air we breathe in a safe and efficient manner.

Clean air. All day. Every day.

Great stuff. Didn’t know Alaska and Hawaii electric rates were so high.
