It’s that time of year again when North India is covered with a large sheet of smog which is not going anywhere before summer. The Air Quality Index (AQI) goes all-time high during this period and remains most of the time in the hazardous category which is harmful to you and your loved ones. Now, buying an air purifier is the best investment you can make. However, there are many factors that you need to consider before opting for an air purifier. This article, not only will we tell you the best air purifiers to buy but also the factors that you should consider before buying any air purifier. Let’s check out the best air purifiers available in India right now.

Things to Consider Before Buying an Air Purifier

Noise Level

Many Air Purifiers produce a lot of noise when they are running at full strength which becomes irritating. The noise is enough to disturb your sleep which is why you should buy an air purifier that produces less noise. 

App Control

Almost all purifiers now come with a dedicated app that tells you almost every detail about the air purifier, current AQI, how harmful it is outside, sleep timer, fan modes, etc. All these can be controlled by your smartphone or tablet, so it’s better to pick an air purifier that has advanced control systems.

Decide Why You Need it

An air purifying device can serve different purposes. Therefore, it is important for you to decide what’s your use case, if you need to clear something specific such as to clear smoke, or for your pets. If you have allergies or Asthma, then pick an air purifier after checking its filter, including HEPA filters, chemical filtration, etc. 

Maintenance Period

Air Purifiers get dirty quickly so they require maintenance after a period of time. You need to replace air filters during the maintenance. Therefore it’s wise to choose an air purifier that has less maintenance period. A HEPA filter can work well for a year, whereas a carbon filter lasts six months. Last, pre-filters can last three months.

CADR Ratings

CADR, also known as Clean Air Delivery Rate, states the volume of air that is cleaned in CFM (Cubic Feet per Minute). It tells whether the air purifier you are buying is powerful enough to clean your living room air. Always prefer a purifier with a high CADR rating as it will be able to clean the air quickly.
