10 Best Air Purifier With Permanent Filters 2025 in the United States

The Shark Air Purifier HP152 is designed for large rooms up to 650 square feet, making it suitable for bedrooms, kitchens, living rooms, and basements. It features a HEPA filter with NeverChange technology, which lasts up to 5 years without needing replacement. This can save users over $300 in filter replacement costs compared to other units.

The HEPA filter captures 99.98% of dust and allergens, exceeding standard requirements, and the Debris Defense filter helps protect the HEPA layer from larger particles like hair and dust. This ensures the purifier maintains high performance over time. The device also includes an Odor Neutralizer Technology that significantly reduces household odors, releasing a fresh scent throughout the home.

Clean Sense IQ technology automatically adjusts the purifier's power based on real-time air quality measurements, displayed on an LED screen. This makes it easy to monitor and maintain clean air. The unit operates quietly, with dimmable lights to minimize sleep disruption, making it a good choice for bedrooms. The Shark Air Purifier HP152 offers robust filtration, large room coverage, quiet operation, and user-friendly features, making it a strong contender for anyone seeking a high-performing air purifier with minimal ongoing maintenance.

The LEVOIT Vital 100 Air Purifier is a solid choice for anyone needing cleaner air in medium to large rooms up to about 788 square feet. Its 3-stage filtration system includes a washable pre-filter plus efficient and activated carbon filters, which tackle common pollutants like dust, pollen, smoke, and pet hair. This means you get a good range of protection against allergies and odors. The purifier is certified by AHAM, so its air cleaning performance has been independently verified, which adds trustworthiness. It runs quietly at just 24 decibels, making it suitable for bedrooms or offices without disturbing your sleep.

The device is compact and easy to place, with top vents allowing flexible positioning even near walls. In terms of maintenance, the pre-filter is washable, which helps save money, but the main filters need replacement every 6 to 8 months, which is typical for this type of purifiers. You’ll also find user-friendly features like a timer, display light control for night use, and a filter change indicator, making it convenient to operate. One downside is that it only works with original Levoit filters, so replacement options are limited to the brand.

Energy-wise, it’s efficient and costs very little to run continuously. Although it is not the cheapest model available, it balances performance and quiet operation well, making it a dependable option for improving indoor air quality in homes with allergy sufferers, pet owners, or those exposed to smoke and odors.

The BLUEAIR 211+ is designed for medium to large rooms, covering around 540 square feet efficiently with its HEPASilent technology. This technology combines mechanical and electrostatic filtration to capture very small particles down to 0.1 microns, which is great for removing dust, pet dander, smoke, pollen, and even bacteria. One notable strength is its quiet operation, running at just 31 decibels on the lowest setting, making it suitable for bedrooms or living rooms without disturbing sleep or daily activities. The air purifier is also energy-efficient, using less power than a standard lightbulb on low settings.

Maintenance is straightforward with washable pre-filters, which help extend the life of the main particle and carbon filters that need replacement about every six months. These genuine Blueair filters are easy to find and maintain optimal performance, though it’s important to budget for replacement filters over time. The 360-degree air intake design allows flexible placement in your room without compromising effectiveness. Users will appreciate the simple one-button control for adjusting fan speed quickly. The purifier also targets odors effectively thanks to its carbon filter, making it a good choice for homes with pets or cooking smells.

Although it doesn’t have automatic sensing or smart features, the manual controls keep things simple. The unit is a bit heavier than compact models but still easy to move around. For those seeking a reliable, award-winning air purifier that balances powerful cleaning with quiet operation and easy upkeep, the BLUEAIR 211+ is well suited for allergy sufferers or anyone wanting cleaner air in larger spaces.
