10 Best Air Purifiers Under 100 2026 in the United States

The Coway Airmega AP-1512HH is a strong choice for anyone looking for an air purifier for rooms up to around 360 square feet. It has a good Clean Air Delivery Rate (CADR) for dust, pollen, and smoke, meaning it cleans air efficiently within its coverage area. Its 4-stage filtration system, including a True HEPA filter, captures 99.97% of tiny particles and also helps reduce odors and harmful gases, which is great for allergy sufferers or those wanting fresher indoor air. The purifier features real-time air quality monitoring through a colored LED, making it easy to see how clean your air is at a glance.

It also offers manual fan speeds and an auto mode that adjusts to air quality, plus an energy-saving Eco mode that kicks in when the air is clean. Noise levels are generally quiet, ranging from about 24 to 54 decibels, so it won't be too disruptive whether in a bedroom or living room. The unit uses about 77 watts of power, which is reasonable for this type of device. Maintenance is straightforward with filter indicators reminding you when to clean or replace the filters, though you'll need to buy replacements separately.

One thing to note is that while the device covers moderate-sized rooms well, it might not be ideal for larger spaces. Also, it isn’t smart home compatible, so it won’t connect to apps or voice assistants. Given its strong filtration, ease of use, and positive user reviews, the Coway Mighty AP-1512HH provides good value for those needing effective air purification without advanced smart features.

The LEVOIT Core 200S-P Air Purifier is a compact and versatile option for those on a budget. It features a 3-in-1 HEPA filter that effectively removes 99.97% of dust, pollen, and airborne particles as small as 0.3 microns. This makes it particularly beneficial for individuals with allergies or those looking to improve air quality in small to medium-sized rooms up to 183 square feet.

The purifier operates quietly, with noise levels as low as 27dB, which is excellent for bedrooms and other quiet spaces. Additionally, it includes smart features such as WiFi connectivity and compatibility with Amazon Alexa and Google Assistant, allowing for remote control and voice commands through the VeSync app. However, it's important to note that the air purifier is designed for use in the United States only, with a voltage of 120V.

While it offers good performance for its price range, its room coverage is more limited compared to some other models on the market. The maintenance is straightforward, requiring the pre-filter to be cleaned every 2-4 weeks, and it’s essential to use genuine LEVOIT replacement filters to maintain optimal performance. The LEVOIT Core 200S-P is a solid choice for smaller spaces, offering quiet operation and smart features, though its coverage area may be a limitation for larger rooms.

The LEVOIT LV-H132 air purifier is a solid choice if you need an affordable device for a small to medium room (up to about 263 sq ft). It carries the AHAM VERIFIDE seal, which means its air cleaning ability has been independently tested and verified, adding confidence in its performance. The 3-layer filtration system includes a pre-filter, a main efficient filter, and an activated carbon filter, which together effectively reduce dust, pollen, smoke, and odors — making it especially good for allergy sufferers or those sensitive to smoke and pet smells.

One of the standout features is how quietly it operates, with noise levels around 28 decibels, so it won’t disturb your sleep if you leave it running overnight. Energy use is low at just 11 watts, which helps keep electricity costs down. Maintenance is straightforward with official replacement filters available (model LV-H132-RF), but using off-brand filters could harm the unit.

The purifier's room coverage is limited to smaller spaces, so it might not be effective in larger rooms or open-plan areas. While it offers a night light feature with adjustable brightness, some users might prefer multiple fan speeds or smart controls, which this model lacks. Also, the device needs about 15 inches of clearance on all sides for best airflow, so space placement might be a consideration. This LEVOIT model is a dependable, quiet, and energy-efficient air purifier ideal for bedrooms, nurseries, or offices under 300 square feet. Its verified filtration quality and low noise make it stand out in its price range, though it’s best suited for users who don’t require coverage for larger areas or advanced control features.
