Whether an air filter can be cleaned and reused depends entirely on the type of filter. Reusable filters (often made of washable foam, cotton, or synthetic materials) can be washed, whereas disposable pleated paper or HEPA filters will be permanently damaged and lose their filtering efficiency.
Yes, you can clean and reuse air filters, but only if they are explicitly designed to be washable. Using water or compressed air on standard paper disposable filters will ruin the filter material, reduce air quality, and risk damaging your equipment.
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.
Asthma and Air Filters. If you have asthma symptoms, an air filter or room air cleaner may help you to breathe better. The same is true for those with hay fever (allergic rhinitis) or COPD (emphysema or chronic bronchitis). If you live with a smoker, an air filter or room air cleaner is likely to be helpful.
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.
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.

5 Common Signs It's Time To Invest In An Air Purifier
Worsening Indoor Air Quality
This can lead to general discomfort, fatigue, and even “sick building syndrome,” where occupants consistently feel ill due to poor air quality. You might notice lingering odors, stuffy air, or even a film of dust covering furniture — all signs that your air filter needs attention.
An air purifier is generally the better choice for managing asthma. Air purifiers actively remove airborne triggers like dust, pet dander, pollen, and mold spores. Humidifiers only add moisture, and excess humidity can actively encourage the growth of mold and dust mites, worsening asthma.
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.
Air purifiers do not actively remove moisture from the air, but their fans circulate air which increases evaporation. This airflow can dry out your nasal passages and worsen sinus irritation—especially if you sit directly in the breeze or live in an already dry climate.
Apply Air Filter Cleaner: You can purchase an air filter cleaner at our parts department or make your own cleaning solution in a 2:1 ratio of water to mild laundry detergent. Shake your solution and spray it on the filter. Let it soak in for a minute or so. Scrub with a Brush: Scrub the filter gently with a soft brush.
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.
A dirty filter is a breeding ground for bacteria, and too much build-up will cause the filter to break down and let some gunk through. Your AC will then circulate the dirty air through your home, which can lead to a sore throat from air conditioning. That's why most modern window ACs include a “Check Filter” light.
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.
While air purifiers are designed to help you breathe easier, certain models (especially those with ionizers) or improperly maintained units can cause negative side effects. The most common issues include throat irritation, headaches, and respiratory flare-ups caused by byproducts like ozone.
If you're wondering if it's time to change your HEPA filter, look out for these signs.
The five most common symptoms of asthma are shortness of breath, a persistent cough, wheezing, chest tightness, and sleep disruptions caused by breathing difficulties.
The best sleeping position to clear your lungs is on your back with your head and chest elevated at a 30 to 45-degree angle. This position uses gravity to naturally drain mucus away from your upper airways.
VITAMINS BENEFICIAL FOR LUNG 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.
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.
Monolithic slab foundations are an effective way to minimize radon entry. For slab on grade homes in warm climates, pour foundation and slab as a single monolithic unit. Use materials which will minimize concrete shrinkage and cracking (larger aggregate sizes and proper water-cementitious ratio).
