Tips for Purchasing an Air Purifier
We all know that clean air is better for our health. There is a lot of air cleaning products on the market. Hopefully this guide will help you to understand what all of the acronyms mean and will make the selection process of your air purifier easier and most of all you get exactly the features that fit your needs. Below are some tips for purchasing an air purifier.
OEM stands for Original Equipment Manufacturer. This means that it is the manufacturer of the product and also the provider for replacement parts when the parts in the product need to be replaced. Generic parts may be available on the market, which can save a little bit of money, however the quality of the generic parts can never be guaranteed. When OEM replacement parts are purchased you are assured the same quality and fit as the original parts, because they are the same.
CADR stands for the Clean Air Delivery Rate. The higher the CADR number indicates a higher filtration rate and therefore a more efficient filter. Typically it is recommended to purchase an air cleaner that has a CADR around 67% of the total area of the room where you want to filter the air. The CADR number is marked on the box and indicates the performance of the air purifier when used with all OEM parts and not cheaper generic parts. Using generic parts could lead to a reduction of the CADR rate.
HEPA stands for High Efficiency Particulate Air. It is a specific type of filter. HEPA filters originated during World War II as they were originally designed to prevent the inhalation of radioactive particles. Today, HEPA air purifiers are some of the best air cleaners available on the market as they can remove particles as small as 0.3 microns!
MERV stands for Minimum Efficiency Reporting Value, which is a number that represents the efficiency of the filter. The number shows the filters ability to remove particles from the air. A low MERV value indicates to the consumer that the filter is not as efficient at removing the particles, while a high MERV value indicates a filter that is highly efficient at removing the particles. The MERV value is the standard used by all of the air purifier manufacturers and makes comparison of multiple air purifier models extremely easy.
