Additional Features

Most important from
742 reviews

Noise Level
The sleek, bladeless design looks modern and operates quietly enough to be suitable for sleeping or working without distraction.
Additional Features
Combines effective cooling with high-quality air purification, delivering noticeable improvements in air quality especially during allergy season.

The Dyson Purifier Cool TP07 is a well-designed air purifier that combines a true HEPA H13 filter with a fan, making it useful for both cleaning air and providing cooling. It uses advanced Air Multiplier technology to circulate purified air effectively throughout a room of up to about 99 square feet, which is suitable for small to medium rooms like bedrooms or offices. The HEPA filter is fully sealed within the machine, ensuring that captured pollutants don’t escape back into the air. One nice touch is the real-time air quality monitoring displayed on the device and accessible via the Dyson app, allowing you to track pollution levels easily.

Noise-wise, the purifier can reach up to 78 dB, which is on the louder side, especially at higher fan speeds, but it includes a quiet Night mode for use while sleeping. Filter replacement is straightforward, with notifications when it's time to change, though the cost of genuine Dyson filters can be higher than average. Extra features include smart controls through voice assistants and a remote, plus flexible timer settings.

The airflow coverage is somewhat limited compared to larger purifiers, so it might not be ideal for bigger living areas. Its price tends to be premium, reflecting Dyson’s brand and technology. This purifier is an excellent choice if you want a combination of air cleaning and cooling in a smaller space, with smart features and reliable HEPA filtration, but it may be less suited for large rooms or those sensitive to noise.

Buying Guide for the Best Hepa Air Purifiers

When choosing a HEPA air purifier, it's important to understand the key specifications that will determine how well the device will meet your needs. HEPA air purifiers are designed to remove particles from the air, which can help improve air quality and reduce allergens. By understanding the different specs, you can make an informed decision and select the best air purifier for your home or office.
HEPA Filter TypeHEPA stands for High-Efficiency Particulate Air. The type of HEPA filter is crucial because it determines the purifier's ability to capture small particles. True HEPA filters can capture 99.97% of particles as small as 0.3 microns, making them highly effective for removing dust, pollen, mold, and other allergens. HEPA-type or HEPA-like filters are less effective, capturing fewer particles. If you have severe allergies or asthma, a True HEPA filter is the best choice. For general air quality improvement, a HEPA-type filter may suffice.
CADR (Clean Air Delivery Rate)CADR measures the volume of filtered air delivered by an air purifier, indicating its efficiency in removing smoke, dust, and pollen. Higher CADR ratings mean the purifier can clean the air more quickly. CADR values are usually segmented into three categories: smoke, dust, and pollen, with separate ratings for each. To choose the right CADR, consider the size of the room where the purifier will be used. Larger rooms require higher CADR ratings to ensure effective air cleaning.
Room Size CoverageThis spec indicates the maximum room size that the air purifier can effectively clean. It's usually measured in square feet. To ensure optimal performance, match the purifier's room size coverage with the size of your room. For example, if you have a 300 square foot room, choose a purifier rated for at least that size. Using a purifier in a room larger than its rated coverage will reduce its effectiveness.
Noise LevelNoise level is measured in decibels (dB) and indicates how loud the air purifier will be during operation. Lower decibel levels mean quieter operation, which is important if you plan to use the purifier in a bedroom or office. Noise levels can range from around 20 dB (very quiet) to over 60 dB (comparable to normal conversation). Consider your sensitivity to noise and where the purifier will be used when choosing the right noise level for you.
Filter Replacement Frequency and CostHEPA filters need to be replaced periodically to maintain the purifier's effectiveness. The frequency of replacement can vary from every few months to once a year, depending on the model and usage. Additionally, the cost of replacement filters can add up over time. Check the manufacturer's recommendations for filter replacement and consider the ongoing cost when choosing a purifier. If you prefer low maintenance, look for models with longer-lasting filters or lower replacement costs.
Additional FeaturesSome HEPA air purifiers come with additional features such as air quality sensors, auto mode, timer settings, and remote control. Air quality sensors can automatically adjust the purifier's settings based on the detected air quality, providing convenience and energy savings. Timer settings allow you to schedule the purifier to run at specific times. Remote control offers ease of use from a distance. Consider which additional features are important to you and how they can enhance your user experience.
