Buying an air purifier can be a tedious task with such a long list of technical jargons available. For a common man, it becomes a little difficult to understand what does cadr mean? all of these from a technical point of view but we have made these technical terms and options easier in a form of a quick guide. The choice of a good air purifier for your home is an important decision as our bodies depend so much on the quality of the air that we are breathing. Hence, a few technical parameters associated with the air purifiers like the ACH and CADR must be carefully examined beforehand. We have a quick and easy explanation of the technical jargons along with their use in the working of different kinds of air purifiers.
ACH is nothing but the number of times the air purifier is capable to change the air in an hour. It is the number of air exchanges per hour which directly relates to the efficiency of an air purifier. ACH is a parameter which is dependent on the fan speeding and also on the size of the room, in which air purifier is going to be installed. If you have researched a little about the air purifiers then you must have been aware of the most superior type of air purifier. Yes, we are talking about the HEPA filters. These are not exactly purifiers but air filters which are capable to remove air impurities to an extent of 97.97%. HEPA filters come up with at least 4 to 5 ACH and are quite effective in places where there are chances of smoke and other dangerous impurities. They are quite effective in combating with contaminants of even 0.3 microns in size. Apart from ACH, what else needs your attention is CADR. It is actually defined as the clean air delivery rate. Carbon air filters are said to be best for controlling air impurities such as bad gases, bad odour and fumes. Carbon filters are widely used in households to get rid of pet odours and dust particles from carpets and wooden furniture.
What’s the benefit of having an air purifier with good CADR (Clean Air Delivery Rate) is that you would not believe how fast it is going to clean the indoor air and environment. All the smoke, dust and pet odour is very quickly caught by good CADR filters. The people who are more prone to allergies in various seasons must think of installing a carbon filter in their homes that comes with a good ACH and CADR technology. Another important jargon about air purifiers is the CFM. It stands for Cubic Feet Per Minute. This jargon determines how well the air purification will be. It basically calculates the cubic feet per minute that flow through the air purifier and improve the air quality. All these parameters decide how well the air filter can purify the air by removing a volume of air irritants and impurities.
