Air Purifier Filters – Do You Want To Clean Or Replace?

Executive Summary about Air Purifier By Peter Clark

Air purifier filters can have a huge impact on the choice of air purifier we choose to buy, as many of us do not wish to incur the time and expense involved with regular replacement of these air cleaning filters.

One of the most effective air cleaning technologies available today is that used in the HEPA air purification systems, said to remove 99.97% of particulates from the air. This type of air cleaner, however, employs special air purifier filters, which must be changed on a regular basis in order to maintain the system’s efficiency.

There are also air purifiers available which don’t need air purifier filters; electronic air purifiers do not require air cleaning filters to work. Better those particles on your air purifier filter than in your lungs!

Quiet Air Purifier – What You Should Know Before Purchase

Executive Summary about Air Purifier By Ed Sherbenou

air purifier

Several premium air purifiers are loud on high, but offer as many
as six speeds for useful quiet air purification.

The Decibel (dB) scale measures noise in objective terms.

Quietest air purifier: 15 dB(A)

Soft whisper: 20 dB(A)

Good air purifier on low: 32 dB(A)

Ordinary air purifier on low: 36 dB(A)

Refrigerator: 50 dB(A)

Normal conversation: 60 dB(A)

The air purifier industry has no standards for noise levels. Noise levels greater than 50 dB(A) can make quiet conversation impossible.

Most air purifiers have a fan to move air. Moving air makes noise.

A bigger air purifier can clean the smaller room on lower speeds,
often quietly. A smaller unit will have to run on high continuously, and most smaller air purifiers are noisy on high. For example: 40dB(A)@212cfm is pretty quiet for the air being cleaned.

Consumers can avoid “quiet air purifier” disappointment by demanding true sound data from manufacturers, and installing a larger model than builders recommend for their room.
