NASA does not officially "approve" or endorse commercial products. However, the agency licensed and co-developed space technologies that various commercial brands use in their air purifiers.
Airocide's Unique Air Purification Technology
Airocide is the NASA air purifier. Our technology removed harmful VOCs from the International Space Station and the Columbia shuttle. It made the air safe for our astronauts, and the food they need. It does not matter how challenging the environment is.
The best air purifier depends on your room size and specific needs, but the Blueair Blue Pure 311i Max is widely recommended as the best overall choice. It delivers top-tier smoke and particle filtration, operates quietly, and is highly energy-efficient, making it perfect for medium to large living spaces.
Yes, air purifiers can be highly beneficial for managing COPD (Chronic Obstructive Pulmonary Disease). By removing airborne irritants like dust, pet dander, and smoke, they reduce the triggers that cause coughing and shortness of breath. They can even improve cardiovascular health markers associated with the disease.
NASA's landmark Clean Air Study identified several common houseplants that actively filter out airborne toxins like formaldehyde, benzene, xylene, and ammonia. NASA recommends placing about one plant per 100 square feet of indoor space to maximize their natural air-filtering capabilities.
Research has shown that English Ivy can eliminate up to 78% of airborne mold within 12 hours. This makes it particularly useful in humid areas like bathrooms and basements where mold growth is more common.
Hospitals primarily use heavy-duty, commercial-grade air purifiers equipped with Medical-Grade (H13 or H14) HEPA filters, which capture 99.97% to 99.995% of airborne particles down to 0.3 microns. These systems typically incorporate powerful activated carbon filters to remove VOCs and UV-C light to sterilize trapped pathogens.
The generation of secondary pollutants
Certain purification technologies carry the risk of incomplete reactions: the chemical breakdown of targeted pollutants can then generate secondary irritant pollutants, sometimes even more toxic than the eliminated component!
Consumer Reports names Blueair as its top-rated air purifier brand overall, highlighting its superior particle removal, quiet operation, and high reliability.
The best air purifiers for lung disease (such as asthma, COPD, or pulmonary fibrosis) use True HEPA or HyperHEPA filters to capture dangerous microscopic irritants. For optimal lung health, always avoid any air purifiers that produce ozone (e.g., ozone generators or ionizers), as these can irritate and inflame your airways.
Finding the right air purifier depends on your budget, room size, and specific needs (like pet dander, smoke, or VOCs). Top-rated brands generally excel by combining true HEPA filtration with high airflow rates and smart features.
Yes, it is perfectly safe and highly recommended to sleep with an air purifier on. Running one overnight helps remove allergens like dust, pollen, and pet dander, which can significantly improve your sleep quality and ease nighttime congestion.
Yes, air purifiers are absolutely legit. Backed by the EPA and independent health studies, true HEPA air purifiers are proven to remove up to 99.97% of airborne particles like dust, pollen, pet dander, mold spores, and smoke. They offer genuine, measurable relief for allergy and asthma sufferers.
Because different spaces require different strengths, there is no single "number one" for everyone. However, the Levoit Core 600S and Levoit Vital 200S are widely considered the best overall picks, offering the ultimate balance of heavy-duty cleaning power, smart features, and affordable replacement filters.
Common houseplants like the Snake Plant, Peace Lily, and Spider Plant are excellent natural filters. They help remove airborne toxins (like formaldehyde and benzene) from your home's air.
NASA funded the development of an ethylene scrubber for the International Space Station that has subsequently proved capable of purifying air on Earth from all kinds of pathogens and particulates. Airocide manufactures purifiers that keep the air clean in industrial kitchens and refrigerators, hospitals and hotels.
Yes, air purifiers effectively remove airborne dust from your home. By continuously pulling in surrounding air and forcing it through a True HEPA filter, they trap 99.97% of particles as small as 0.3 microns, including dust mites, pet dander, pollen, and microscopic fibers.
To filter particles, choose a portable air cleaner that has a clean air delivery rate (CADR) that is large enough for the size of the room or area in which you will use it. The higher the CADR, the more particles the air cleaner can filter and the larger the area it can serve.
Is it safe to run an air purifier all day? Yes, most modern filtration-based air purifiers are designed for continuous operation.
For people with allergies, scientific studies have shown that air filtration reduces these airborne allergens and may provide some relief. Experts recommend two types of filtration: For a single room, look for an air cleaner with a HEPA (high-efficiency particulate air) filter.
Follow the 2/3 Rule
As a rule of thumb, the CADR of your air cleaner should be equal to at least two-thirds of the room's area. For example, a room with the dimensions of 10 feet by 12 feet has an area of 120 square feet. It would be best to have an air cleaner with a smoke CADR of at least 80.
Top 5 True HEPA Air Purifiers
The best rooms for an air purifier are your bedroom (where you spend 8+ hours breathing and recovering) and your living room (a high-traffic area with upholstery and pets). The ideal placement is near the specific pollution source.
Air purifiers without ionizers rely entirely on physical filters (like True HEPA and activated carbon) or thermodynamic heat sterilization to clean the air, rather than releasing charged particles into the environment. This ensures no ozone byproducts are generated, making them significantly safer for individuals with asthma and respiratory sensitivities.
