Mark Richardson is a renowned health practitioner and an expert on allergies. He answers the following ten questions about air purifiers.
Which is the best technology in an air purifier that helps in relieving allergies?
This will depend on the type of allergy the person has. But it is advisable to go for HEPA (High Efficiency Particle Arresting) technology as it is proven to remove 99.97% of particles present in the air, as it has the capacity to capture particles which measures as small as 0.3 microns.
What about allergies caused by Mildew and Mold?
HEPA filters will remove spores from the air but will not kill them. To kill the mildew and mold present in your house you need to opt for purifiers having Tio2 and UV technologies.
What about allergies caused by pet dander?
HEPA filter again is the best and you can have a pre-filter installed that will capture dust and hair so that your HEPA lasts longer.
What about allergies caused by dust?
The same answer as the last.
How would you rate Oreck air purifiers?
Oreck uses electrostatic technology to capture pollutants that are air borne. Many allergens are without a charge and hence will not be captured by this technology. The absence of a HEPA filter in this purifier reduces its effectiveness.
How often should a HEPA filter be replaced?
A good quality HEPA filter having 0-size should last an average of nine to twelve months under normal conditions. People should be careful not to over spend on these filter replacements as some companies put a hefty price tag on the replacement filters once you have bought the air purifier from them. A replacement filter of a good size should not cost you more than $40.
How long will the purifier take to clear the air?
If you have installed one with the right technology your purifier should clear the air in several hours. Mildew and mold should be removed in about seven hours.
What would be a reasonable price of a good air purifier?
Do not spend more than $300 for a unit which uses multiple technologies and is effective for the bedroom or living room.
Is the machine required to run all the time?
To save on electricity go for machines which have a dust and allergen sensor. This will automatically adjust the machine's running time.
Can you recommend a machine?
Go for models which use allergen sensors and have about nine technologies that include HEPA, Tio2, UV, Electrostatic and Carbon.
