When you buy an air purifier, you need to look for beneficial features like a warranty. An air purifier with a warranty has an after-service offer that guarantees the product will last for the said number of years. In case it fails, you can claim a replacement. Some HVAC contractors may offer an air purifier warranty when installing the whole house air purifier, while others only guarantee air purifier components. For you to get the most out of your air purifier, you should also look out for its HEPA filtration. Size compatibility is also important as air purifiers are more effective when they are compatible with the room size. Consider buying a model that will be effective in a bigger room since the air purifier can still operate in lower settings and be effective, thus saving you energy. Opt for an air purifier that can be effective even when set to be at the lowest noise level. A purifier’s clean air delivery rate(CADR) signifies its overall cleaning speed to clean dust, smoke, and other pathogens from the air. Use a purifier with a CADR of 300 to 400 for average room sizes. The number of times the air in the room is changed in a room should be frequent enough to guarantee its efficiency. An allergic or asthma-prone person should opt for purifiers with at least four times or five times air change per hour rating. Whenever you buy an air purifier, make sure that it has all those features as the warranty covers it all.
