So it’s important that you investigate your options thoroughly. Find out as much information as you can about the products prior to making your purchase. Here are some tips you should be aware of.

The CADR Rating

You need to know about the ratings associated with any air cleaner filter system you may decide to buy. Use these ratings to determine the efficiency and reliability of the air cleaner system that you’re considering.

The Clean Air Delivery Rate (CADR) is a realistic rating system used to evaluate filters. It’s function is to test the effectiveness of a product at filtering out the damaging contaminants and allergens in the air around us.

The rating is shown as a percentage of the filtering capacity of the system. A higher rating means that the product will be more effective at ridding the air of pollen, dust, smoke and other allergens. So when checking these out you should be looking for one with a higher percentage number denoting its superior filtering ability.

The MERV Rating

The MERV, which stands for Minimum Efficiency Reporting Value, is similar to the CADR rating. The difference is that the product manufacturer conducts the efficiency tests. The MERV, also shown as a percentage figure, indicates a rough guide of how effective the system will work on a scale of 1 to 16. You can be sure that the item you have purchased is good value for money if you select one which falls between 6 and 12.

If you suffer from allergies, it’s important to exercise as much control as possible over the environmental triggers that will set off an attack. A good quality air purifier will help you do the job properly.
