Air purifiers are essential for urban living

Types

They come in various types, each utilizing different technologies to clean the air. Here are the main types of them:

HEPA air purifiers - can capture 99.97% of particles as small as 0.3 microns. They are effective against dust, pollen, pet dander, and some airborne pathogens.

Activated carbon air purifiers - use activated carbon filters to adsorb odors, smoke, and volatile organic compounds. They are typically used in conjunction with other filtration methods.

Ionic air purifiers release charged particles that attach to airborne particles, causing them to clump together and fall from the air or be trapped on charged plates within the device. Some models produce ozone as a byproduct, which can be harmful at certain levels.

UV-C Light air purifiers - use ultraviolet light to kill bacteria, viruses, and mold spores in the air. They are often used in conjunction with other types of filtration.

Ozone generators - produce ozone to eliminate odors and kill mold. However, ozone can be harmful to respiratory health, and their use is generally discouraged indoors.

Photocatalytic oxidation purifiers - use a catalyst, typically titanium dioxide, and UV light to break down pollutants at a molecular level, including VOCs and odors.

Smart air purifiers - these are typically equipped with sensors to monitor air quality in real-time and can connect to smartphone applications for remote control and notifications.

How often should i use it ?

You should use it continuously, especially if you live in an area with high pollution levels, allergens, or if you have pets or smoke indoors. Running the purifier throughout the day helps maintain cleaner air and can be particularly beneficial during allergy seasons or when there are elevated levels of smoke or pollen in the air. However, you can adjust usage based on your specific needs, such as using it more frequently in times of high allergen activity or turning it off when the air quality is good and doors and windows are open for ventilation. Regularly assess the air quality and the condition of your filters to determine the best operating schedule for your situation.

How do I know if my air purifier is working effectively ?

To determine if it is working effectively, you can monitor changes in air quality over time by observing improvements in symptoms such as allergies, asthma, or respiratory issues. Many ones come with air quality indicators that change colour based on the level of airborne pollutants, providing a visual cue of performance. Additionally, check the air filters regularly; if they are discolored or dirty, it's a sign that the unit is capturing particles. You can also use an air quality monitor to measure particulate matter or other pollutants in the air, allowing you to compare levels before and after using the purifier. Lastly, consider the noise level; if the purifier is functioning properly, it should operate within its specified sound range.

Can they effectively remove viruses from the air ?

Yes, they can effectively reduce the concentration of viruses in the air, particularly those equipped with HEPA filters and UV-C light technology. HEPA filters capture airborne particles, including larger virus-laden droplets, while UV-C light can deactivate viruses and bacteria. However, they are not a substitute for other preventative health measures, such as vaccination and good hygiene practices, as their effectiveness can vary based on the type of virus, the purifier's specifications, and the overall air circulation in the environment.

What size of it do I need for my room ?

To determine the size, you need for your room, first measure the room’s area in square feet. Look for the air purifier's Clean Air Delivery Rate, which indicates how efficiently it can clean the air in a given space. Ideally, choose one with a CADR rating that matches or exceeds the size of your room. Most manufacturers provide guidelines on which purifiers are suitable for specific room sizes, so referring to those recommendations while considering any unique factors, such as high ceilings or significant allergen sources, can help ensure you select an appropriate model.

How do I clean and maintain air purifiers properly ?

To clean and maintain them properly, start by unplugging the device and following the manufacturer's instructions. Regularly check and replace the filters according to the recommended schedule, as clogged filters can hinder performance. For pre-filters, you can usually vacuum or wash them gently, depending on the material. Wipe the exterior and the intake and output grills with a damp cloth to remove dust and debris, and ensure there’s no obstruction in the air pathways. Keep the surrounding area clean to minimize dust accumulation. Regularly monitor the indicators for filter replacement and ensure that the unit is running efficiently. Finally, place it in a location that allows for optimal airflow, avoiding corners or areas blocked by furniture.
