Neglecting to change your air purifier filter causes a sharp drop in air quality. As the filter fills up, it restricts airflow. This makes the motor work harder—wasting energy and risking permanent damage to the device. Furthermore, the clogged surface can become a breeding ground for trapped bacteria and mold.
A dirty or clogged filter will reduce an air purifier's ability to clean air, so it's important to change them out regularly. If you don't, your air purifier will not be able to function at its best and could even end up costing you more in the long run.
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.
No, HEPA filters cannot remove radon gas. Because radon is a gas, its molecules are far too small to be trapped by standard physical filtration systems.
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.
However, in general, the duration of use required depends on the size of your space and the amount of indoor pollution (which varies throughout the year). This is why most manufacturers will recommend you to leave your air purifier running all day, especially if it comes equipped with an automatic setting.
No, standard air purifiers do not physically remove moisture from the air. They merely cycle air through filters (like HEPA and carbon) to trap pollutants. However, the continuous airflow from the device's fan can increase evaporation from your skin and nasal passages, making the air feel drier.
Radon levels are generally highest during the winter and colder months. This peak occurs because closed windows tightly seal homes and the "stack effect" creates a vacuum that pulls more radon-rich soil gas indoors.
The primary risk factor for elevated radon in homes is the natural decay of uranium in underlying bedrock and soil. Radon gas seeps indoors through structural openings and concentrates in lower, poorly ventilated areas. Combined with an individual's smoking history, exposure significantly elevates lung cancer risk.
A definitive causal link between radon exposure and Parkinson's disease has not been scientifically established. However, some ecological studies and laboratory research suggest an association between high levels of radon exposure and an increased risk of developing neurodegenerative conditions, including Parkinson's.
The evidence is apparent, in chronic respiratory diseases, such as asthma and in cardiovascular health. Technologically advanced air filter systems are now available which efficiently remove particulate matter, resulting in significant health benefits to patients of asthma and cardiovascular disease.
Consumer Reports names Blueair as its top-rated air purifier brand overall, highlighting its superior particle removal, quiet operation, and high reliability.
Early signs of lung disease are often subtle and easy to overlook. Red flags include persistent shortness of breath during normal activities, a chronic cough lasting over 8 weeks, chronic mucus production, and unexplained chest pain.
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!
Some air purifier filters are washable and some are disposable. Check your owner's manual to find out if you have a washable filter. If you tossed your manual, most can be found online. If you don't find that your air purifier or HEPA filter is labeled washable or permanent, then it is not washable.
It's perfectly safe to keep the device running continuously, and the amount of energy it consumes is very small. And the advantages are significant—by running your air purifier all the time, you'll benefit from the best air quality possible, and the cleaner the air, the better for your health!
Alaska has the highest average indoor radon levels in the United States, measuring at an average of 10.7 pCi/L. South Dakota follows closely as the second-highest at 9.6 pCi/L, and Pennsylvania ranks third with 8.6 pCi/L. These levels significantly exceed the EPA's recommended action level of 4.0 pCi/L.
Opening windows can temporarily reduce radon levels by diluting the gas with fresh air, but it is not a reliable or long-term solution. Once you close the windows, radon levels will quickly rise again because the underlying source of the gas remains unaddressed.
Radon is a naturally occurring radioactive gas produced by the decay of uranium and thorium. It is primarily emitted by rocks with higher-than-average concentrations of these elements, including granites, dark shales, phosphate-rich sedimentary rocks, and metamorphic rocks (like gneiss or schist) derived from them.
Radon gas comes from the natural radioactive breakdown of uranium found in nearly all rocks and soils. It naturally migrates up through the ground and gets trapped inside homes, primarily entering through cracks and openings in the foundation.
The radon in your water supply poses an inhalation risk and a small ingestion risk. Most of your risk from radon in water comes from radon released into the air when water is used for showering and other household purposes.
Radon Levels Fluctuate Every Day
It's common to observe radon levels increasing, particularly in the hours before sunrise. This phenomenon happens, again, due to the peak temperature difference between indoor and outdoor environments, often resulting in elevated indoor radon levels during the night.
The ideal indoor humidity level for sleeping is between 30% and 50%. Maintaining this range helps prevent dry skin, irritated sinuses, and congestion, all of which can disrupt restful sleep. Too little humidity can dry out airways, while too much can promote mold growth and dust mites.
High or low humidity, particularly during winter months, can trigger your allergies and humidity is a bigger factor in whether or not your sinuses are dry. Adding an air purifier can help relieve your allergies by removing the particles in the air but they do not impact moisture in the air.
Allergies: Humidifiers can add moisture to dry air that contains allergens and help you breathe easier by reducing sinus inflammation. They can even help with non-allergy sinus problems. Dehumidifiers can help dry excessively moist environments where allergens like dust mites and mold can thrive.
