How To Select Air Purifiers
If you want to buy an air purifier machine, there are factors like the cost, efficiency, durability and the filter replacements that you need to consider. Nowadays, air purifiers are usually equipped with HEPA filter which is very good for filtering dust, bacteria and air pollens.
To rate how well an air purifier is, CADR is used and it stands for Cleaning Air Delivery Rate. You will be able to have cleaner with higher number of CADR on the air purifier machine. The Whirlpool AP51030K is designed to filter the air in medium to large sized rooms up to 500 square feet with a CADR of 315.
Another common filter is an activated carbon filter sometimes called charcoal filter, depending on the brand of air purifier. Carbon filters have been used over the centuries to purify water and it wasn’t until the early 20th century that the air cleaning qualities of charcoal got discovered. Activated carbon is therefore also one of the materials used in gas masks.
For filtering the micro particles, a HEPA filter will be used and a carbon filter will filter smells and chemicals. Different air purifiers will have different amount of carbon in them. What this actually measures is the amount of activated carbon used in the filter. For people who cannot stand perfumes, a pre-carbon filter will be great for them.
The efficiency for air purifiers is a very important thing that you need to pay attention too. For the HEPA label, it represents the amount of air that is cleaned as the air passes through the filter.
When the filter is working, some air just flow through without getting filtered and this will make it pointless for you to have a filter at the first place. Therefore, it is vital to check the CADR number on the air purifier so that you will be able to get effective air purifiers.
The bottom line is that the filters make up an important part of an air purifier and you should pay attention to this when calculating the overall cost price. Nowadays, air purifiers come with both the HEPA and carbon filters. Some of the more expensive models on the market claim to have permanent filters.
The Honeywell 50250 for example, unlike the Whirlpool AP51030K air purifier, boasts filters that do not need replacement but only need vacuuming instead. Many consumers do not favour the permanent filter as they prefer to replace the filters on a regular basis so that they can be sure that their air is clean.
