Think of the AQI as a yardstick that runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality.
Clean air is good for people to breathe. On a hot day with no wind, the air can feel heavy and have a bad smell. Once in a while, the air can even make your chest feel tight, or make you cough. When too much dirt and chemicals get into the air, the air is dirty or polluted.
Harmful emissions come from heating, cooling and powering businesses and industrial operations, as well as from manufacturing processes. Wildfires, flooding, hurricanes and other natural events can create unhealthy air, especially for people with lung disease.
Simple things you can do to improve your indoor air quality include: Reduce dust by vacuuming regularly and using a microfiber or damp cloth for dusting. Reduce humidity to avoid mold and mildew buildup and change appliance filters regularly. And make sure to test your home for dangerous gases like radon.
A 2022 study found that devices with HEPA filters are reasonably successful at filtering out airborne COVID-19. However, other experts note that air purifiers won't clean contaminated surfaces and can't prevent people from contracting COVID-19 if they inhale it from an infected person close by.
So, does a humidifier clean the air? No. Their function neither improves the quality of the air nor reduces the particles in it. Instead, humidifiers are devices that release water vapor or steam into the air to increase humidity levels in a room or throughout the home.
You can use a testing device or hire an indoor air quality specialist. Either option is good. Radon and mold tests are usually recommended to test home air quality and other home tests when buying a new home. If you want an accurate way to test the air quality in your home, you may consider hiring a specialist.

How long does it take an air purifier to clean a room? This mainly depends on the setting of the air purifier, your current air quality, and the size of your room. It can take your air purifier 30 minutes to clean air in a small room. For larger rooms, it can take up to 2 to 3 hours.
Beeswax and soy candles usually burn cleaner than paraffin wax. Furthermore, beeswax candles can actually clean your air by releasing some negative ions that easily bind with toxins to help eliminate them from your indoor air.
Excess Moisture. Moisture is one of the most important and least recognized indoor pollutants, affecting both human health and the health of the building.
The most dangerous of these indoor air pollutants are the colorless and odorless gases nitrogen dioxide and carbon monoxide. Nitrogen dioxide can lead to shortness of breath, and irritation of the mucous membranes in the eye, nose, and throat.
Consider Purchasing An Indoor Air Quality Monitor
If you want to monitor your indoor air quality proactively, you can invest in an air quality monitor. These devices constantly check the indoor air quality and provide feedback about the levels of different pollutants.
EPA's AirNow mobile app provides a simple interface for quickly checking current and forecast air quality information for planning daily activities and protecting your health.
The primary way airtightness is tested is via a blower door test. During a blower door test, a fan is installed in the door or window of the building to be tested. The blower door machine then pressurises or depressurises the building to force air through any cracks or gaps in the building envelope.
While a humidifier can add moisture to the air, it is not designed to remove pollutants or allergens. If you want to improve the air quality in your home or office, an air purifier is a better choice.
What are the downsides of air purifiers? There aren't a lot of downsides to having an air purifier in your home aside from the financial investment. Many ionizers, especially older models, can generate ozone when they are operating, which is known to exacerbate asthma.
