CADR (Clean Air Delivery Rate)
It noticeably improves indoor air quality by reducing allergens, dust, and pet odors, making breathing easier and the environment fresher.
Noise Level
The purifier operates whisper quiet on low settings and maintains a gentle hum even at higher speeds, perfect for running overnight without disruption.
Maintenance and Filter Replacement
Setup is effortless—just plug in and start, with a helpful filter change reminder that takes guesswork out of maintenance.

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.

The Dyson PureCool Hot + Cool HP04 is a multi-functional air purifier that also works as a heater and fan, making it a versatile choice for year-round use. It uses a sealed HEPA H13 filter, which is excellent for capturing fine particles like dust, pollen, pet dander, and even volatile organic compounds, ensuring high air cleaning performance. The purifier covers up to 800 square feet, which is quite spacious and suitable for medium to large rooms.

It features advanced sensors that detect and report air quality in real-time, plus an app for remote control, adding convenience. The Air Multiplier technology helps project purified air evenly across the room. This model is refurbished and weighs about 12.4 pounds, which might be a bit heavy compared to simpler models under $100. Maintenance involves replacing the HEPA filter, which can be more costly than standard filters, especially since Dyson filters tend to be pricier.

If you are strictly looking for a budget air purifier under $100, this purifier might be more than needed. However, for those who want strong filtration combined with heating and cooling features, it offers good value in a single device.

Buying Guide for the Best Air Purifiers Under 100

Choosing the right air purifier can significantly improve the air quality in your home, making it healthier and more comfortable to breathe. When selecting an air purifier, it's important to consider several key specifications to ensure you get the best fit for your needs. Here are some essential specs to look at and how to navigate them.
CADR (Clean Air Delivery Rate)CADR measures the volume of filtered air delivered by the air purifier, indicating its effectiveness in removing pollutants like dust, pollen, and smoke. Higher CADR values mean faster and more efficient air cleaning. For small rooms, a CADR of 60-100 is sufficient, while larger spaces may require a CADR of 200 or more. Choose a CADR based on the size of the room you want to purify.
Filter TypeAir purifiers use different types of filters to remove contaminants. HEPA filters are highly effective at capturing small particles, making them ideal for allergy sufferers. Activated carbon filters are great for removing odors and gases. Some purifiers combine both types for comprehensive air cleaning. Consider your specific needs, such as allergies or odor removal, when choosing the filter type.
Room Size CoverageThis spec indicates the maximum room size the air purifier can effectively clean. It's usually measured in square feet. Small purifiers cover up to 150 sq ft, medium ones up to 300 sq ft, and large ones can handle 500 sq ft or more. Match the room size coverage to the dimensions of the space where you plan to use the purifier to ensure optimal performance.
Noise LevelNoise level is measured in decibels (dB) and indicates how loud the air purifier is during operation. Lower dB values mean quieter operation, which is important for bedrooms or offices. Air purifiers typically range from 20 dB (very quiet) to 60 dB (normal conversation level). Choose a noise level that won't disturb your activities or sleep.
Energy EfficiencyEnergy efficiency refers to how much power the air purifier consumes. Look for models with Energy Star ratings, which are designed to use less energy without compromising performance. This is important for long-term use, as it can save on electricity bills. Consider how often you'll use the purifier and choose an energy-efficient model to keep costs down.
Maintenance and Filter ReplacementAir purifiers require regular maintenance, including filter replacements. Check the frequency and cost of replacing filters, as this can add to the overall expense. Some models have washable filters, which can be more economical. Consider how easy it is to maintain the purifier and the availability of replacement filters when making your choice.
