Prior to buying an air purifier for home, it is necessary to understand the different types available and which of those would be the most suitable for your needs. For that, you need to identify the main goal of your air purifier. This will make it easier for you to choose the right kind of purifier. The tips given below will be able to guide you further.
What Is Your Need?
As mentioned, this is the first step that you need to clear. What are the main pollutants you want to combat such as pollen, allergens, smoke, gas or dander or is it simply the desire for cleaner air? Identify the contaminants to be removed from the indoor air before going on to the next step, which is looking at specific attributes.
The Efficiency of the Purifier
The efficiency of the filter determines the efficiency of the air purifier. It is measured by the size of the particles it can capture. It is an excellent purifier if it can capture something as small as 0.3 microns. The size of most common allergens is between 0.3 and 5 microns and a HEPA filter is very much capable of capturing these and any other contaminant 0.3 microns or bigger.
For contaminants smaller than 0.3 microns, HEPA filters are not very effective and should be replaced by an ionizer, activated carbon filter, or a UV purifier.
The Rate of Providing Cleaner Air
CADR or Clean Air Delivery Rate indicates the volume of air that can be cleaned of a particular pollutant by the system in an hour’s time. The higher the CADR, a higher number, the higher is the efficiency of the product for the pollutant.
CFM or Cubic Feet per Minute measures the volume of air that passes through the air purifier in one minute. A lower CFM is not of much value as you will not be able to get the worth of your investment. An air purifier for home is powerful if it has a CFM of 350-400.
It does not help to have one kind of pollution removed at the cost of another. So, what you really need to look for is a purifier, which does its work quietly. The product will have a decibel rating associated with it on its packaging. You can choose based on the sound level you are comfortable with. A larger unit would be a better choice as you can choose to run it at a lower speed, thus reducing the noise levels.
The product is likely to be less reliable if it comes cheap and/or if the company does not give you a warranty. You will find yourself investing far more than your budget in your purifier if you choose such an option. If you want the best air purifier in India, go for a reputed manufacturer and look for a five-year warranty on the motorized parts. You will probably not need to use the warranty if you clean and replace the filters regularly.
Looking at these features becomes easy if you have a certain brand in mind. Often a reputed manufacturer will have a range of options for the best air purifier in India to suit different needs. You will be able to find purifiers with HEPA filters, ionizer, active carbon filters, and UV filters in various combinations. The right choice can always start with the right brand.
