Key Elements to Consider when Evaluating Air Purifiers


With the surge in pandemics like the SAARs and COVID 19, air purifiers have proven to be more reliable in freshening and purifying the air in most homes. As an air purifier enthusiast, you might want to evaluate the effectiveness of a purifier to suit claims that it can over protection against COVID 19. Visit to check on the capabilities of the most recent purifiers in 2021. To analyze these purifiers, you will need to use a given set of factors to compare and contrast different varieties. Read on to get most of what you need to know about evaluating air purifiers.

Filter Technologies and Design

You might think that only the size and amount of media for a filter matter in evaluating an air purifier. Well, you need to expand your horizons and analyze the filtration system. A better purifier should have a four in one filtration system. This means having initial plastic filters that remove large particles from the system, Antibacterial cloth filters, medical-grade HEPA filters and carbon filters. Having this complete set of filters will ensure the removal of tiny micro-particles that are not easily filtered out by simple filtration systems.

Purifier Size and the CFM Output

The purpose of the purifier dictates the size and output that is needed. Purifiers used for commercial purposes or halls need to have a large output compared to residential ones. Knowing the size or rather the volume of the room is vital in calculating the CFM that is required hence the size of the air purifier that you need. The CFM is calculated per hour and indicates the output potentiality of the air purifier in question.

Air Changes per Hour 

This is the only way to be assured of protection. The air changes per hour give you the information on the amount of protection you are likely to get. Having a high number of changes per hour will mean an increase in the amount of protection you receive. The opposite is true. Regular filtration, also known as changes per hour, will also mean fewer contaminants or minimal pathogen survival. It is critical either to check on the fan power rating for your purifier. Purifiers with little or low fan power tend to be ineffective. It would be best if you did a proper analysis of the length of the fan circle. Shorter fan circles mean less efficiency, especially for larger rooms.

Fan Design and Enclosure 

The shape and the overall construction of an air purifier meant for commercial purposes, is of great value in evaluation. This dramatically affects the appearance, amount of noise discharged and type of bearings used or that are to be best used. The kind of materials used for the enclosure will mean shorter or longer durability of the air purifier in question. Metallic enclosures tend to be durable as compared to plastic or fibre built enclosures. You need to look out if the design is ideal for purification purposes. A good design should have a strategic position for breathing in contaminated air and breathing out fresh or air that has been purified.
