Top 5 Good Air Purifiers For Delhi NCR In December 2025: Survive the Smog

The Coway Airmega 150 air purifier for home is frequently the choice of long-term Delhi residents due to its robust filtration system and exceptionally low maintenance cycle. Equipped with a Green True HEPA Filter (H13 grade), it boasts a claimed filtration efficiency of 99.999% against ultra-fine particles down to PM 0.01, including viruses, bacteria, and allergens. Its multi-stage filtration including an easy-to-clean pre-filter, a deodorization filter, and the primary HEPA filter ensures comprehensive air scrubbing. What truly sets the Airmega 150 apart is its stated filter life of 8500 hours, translating to approximately 1.5 to 2 years of use in moderate conditions. While compact, it offers a solid Clean Air Delivery Rate (CADR) suitable for mid-sized bedrooms and study rooms, making it a reliable, long-term investment that minimizes the hassle and cost of frequent filter replacements during Delhi’s peak pollution months.

• Main USP: Longest Filter Life & PM 0.01 Filtration.
• User Feedback Summary (Amazon): Highly praised for its durability and silent performance, especially in bedrooms. Users frequently confirm that the filter lasts well over a year, even in highly polluted NCR areas. The simple, non-smart interface is a plus for those who prefer ease of use over complex features.

Honeywell has established itself as a reliable brand in the Indian air purifier market, and the Air Touch V1 represents their compact and efficient offering.

The unit is designed for smaller spaces, covering around 235 sq. ft., making it ideal for standard bedrooms or home office cabins. Its low power consumption and quiet operation, aided by an advanced DC motor, provide clean air without causing a spike in your electricity bill or disrupting your sleep.

The AGARO Royal is positioned as a powerhouse, featuring a high CADR of 300 m3/hr, which allows it to quickly clean the air in mid-sized living rooms or larger master bedrooms (up to 400 sq. ft.). Crucial for Delhi's air, it employs a 4-stage purification process that includes an H13 True HEPA filter, a Silver Nano Particle filter to tackle bacteria and viruses, and an activated carbon layer for gaseous pollutants. The high CADR is essential for December, as it means the unit can cycle the air multiple times per hour, rapidly bringing down the AQI from a severe outdoor level to a safe indoor level. The inclusion of a real-time PM indicator and multiple operational modes gives the user precise control over their environment, making it a strong contender for those needing fast, high-volume air cleaning.

Unlike the tower models above, the Reffair AX30 [MAX] serves a critical dual role: a dedicated car air purifier that is also suitable for small personal spaces, such as a desktop or a small 100 sq. ft. cabin. Recognizing that Delhi NCR residents spend considerable time commuting in highly polluted air, this device addresses a major gap. It features an H13 True HEPA filter and Activated Carbon to clean the air inside your vehicle effectively. Its unique feature is the Plasma Ions Function, which actively neutralizes airborne contaminants and sterilizes the air, complementing the passive filter. The inclusion of an Aromatherapy function also allows users to use essential oils for a more pleasant in-car experience. It is a necessary addition for the long, smoggy commutes experienced in the NCR region.

Sharp’s air purifiers are distinctively known for their proprietary Plasmacluster Ion (PCI) Technology developed in Japan. The FP-J30M-BK model combines this active PCI technology with traditional passive filtration (Pre-filter, HEPA, and Carbon) to provide comprehensive indoor air defense. The PCI technology releases balanced positive and negative ions into the air, which surround and neutralize airborne molds, viruses, bacteria, and allergens before they even reach the filter. This makes it a great choice for allergy and asthma sufferers. The unit covers up to 250 sq. ft. and features the signature 20° Airflow Angle, which helps clean the air near the floor where dust and ultrafine particles tend to settle. The filters also boast a long life of up to two years, making it an excellent balance of technology and low maintenance.

• Main USP: Plasmacluster Ion Technology for Active Anti-Virus and Anti-Mould Action.
• User Feedback Summary (Amazon): Customers frequently report a noticeable absence of musty or damp smells, attributing it to the Plasmacluster technology. It is highly recommended for children's bedrooms and is celebrated for its whisper-quiet night model.
