During winters, air quality rapidly deteriorates, especially in cities like Delhi-NCR. In such a situation, air purifiers have become a necessity for homes. According to experts, it is beneficial to purchase an air purifier only after considering standards such as the correct HEPA filter, appropriate CADR, room size match, filter cost, smart features, and energy efficiency.
Air Purifier Buying Guide: As winters begin in many major cities across the country, air quality reaches dangerous levels, and breathing becomes difficult due to smog in Delhi-NCR. In this situation, air purifiers have become essential for homes. This report explains when and why it is crucial to select an air purifier with the right technology, which features to look for, and how choosing the wrong model can impact your health and finances. Experts state that selecting a machine with the correct HEPA filter, CADR, and appropriate for the room size is vital for family health.
True HEPA Filter is Real Protection
The primary function of an air purifier is to remove microscopic particles present in the air. For this, a True HEPA filter is considered most effective, especially grades H13 and H14. It can efficiently clean a large quantity of PM2.5, smoke, dust, and allergen-causing particles.
Also pay close attention to CADR, which stands for Clean Air Delivery Rate. This indicates how quickly the machine will purify the air. Choosing a model with a CADR equal to or greater than the room size ensures better performance, especially in pollution-prone countries like India.
Choose a Purifier According to Room Size
Every air purifier has a specified coverage capacity. If the room is large and the machine has a small capacity, the effect will be slow, and more electricity will be consumed. Generally, a model with coverage greater than the room's area is better.
Choosing the wrong size means the air is not filtered uniformly, and the purifier does not deliver expected results even after continuous operation.

Understanding Filter Replacement Costs is Important
The initial cost of an air purifier is not everything. HEPA filters may need to be replaced every 6 to 12 months. Therefore, check the availability and price of filters before purchasing.
Replacement filters for many foreign or premium brands are expensive. If filters are not readily available, the purifier could become useless.
Smart Features and Low-Noise Models are Beneficial
Features like multiple modes, PM2.5 indicators, and auto mode make daily use easier. For bedrooms or offices, choosing a low-noise model is better to avoid disturbing sleep or work.
Today, many models come with Alexa and Google Assistant support, allowing you to control them via voice or mobile app.
Power Saving and Easy Maintenance
Energy efficiency is crucial for appliances that run continuously. Models with energy-saving features keep electricity bills low and save costs in the long run.
Also, choose filters that are easy to clean to extend their lifespan and maintain better performance.
Pollution is no longer a seasonal problem. In many cities, a large part of the year is spent amidst poor air. In such a situation, an air purifier has become crucial for health protection. By choosing the right model, you can protect your own health as well as that of children and the elderly.
