Nine questions to ask when buying an air purifer?
Investing in an air purifier can really help your health, improve your environment and make you feel better. So what is important to ask about an air purifier before purchasing?
The air needs to be moved to be cleaned. Ask for the cubic feet per minute (CFM) rating of the air purifier. For good quality air, you want 4 to 6 air exchanges per hour. Meaningful air flow is essential.
An air purifier should be able to remove all three major groups of contaminants. These groups are: particulates, biological contaminants and chemical pollutants. Ask yourself, “Where does the dirt, viruses and chemicals go?”
Find out the capacity of the filters. The more capacity,the better performance you will have and less frequency of changing filters and maintenance. It is important that filters are easy to change and allow for independent filter replacement. It is convenient if you can order replacements easily on the web. Is there an indicator light to let you know when it is time to change the filters?
Check to see if the manufacturer has a good track record of units in the field and strong support system. Check the warranty and ask for a list of current satisfied customers.
Quality construction including excellent sealing is important. If there is bypassing around the filters, contaminants are just getting a free ride around your environment.
An air purifier should be portable and convenient for the consumer to use.
A recycling program shows that the manufacturer is concerned about making the world a greener place.
Ozone is dangerous and can have serious health effects. Check to see if manufacturer has any class-action law suits or complaints.
Some companies will offer rentals of air purifier units as an excellent option to improve you indoor air quality.
It is often asked, “How do I know if my indoor air quality is poor?” Our bodies are extremely sensitive to the air quality. Sneezing, coughing, watering eyes may be indicators of poor air quality. Stale air and odors also indicate problems in the environment. Good quality air should be very neutral. If the air smells like chemicals or fragrance,there is probably an indoor air quality issue that is being covered up. Trust your senses and take appropriate action.
