An air purifier is an incredibly useful device in today's living spaces. It provides clean, bacteria-free air, promoting health and well-being.
Should you buy an air purifier?
If you're wondering whether to purchase an air purifier, let's explore it together right here.
1. Effectively filters small dust particles
Modern air purifiers are equipped with advanced Hepa filters, capable of effectively filtering out coarse dust particles including small particles measuring 0.3 micrometers. Additionally, the machines are equipped with pre-filters and intermediate filters with pollen filters, activated carbon filters, or Titan filters.
With a dense filter system, air purifiers can effectively filter all types of fine and ultrafine dust such as PM10, PM2.5, PM0.3, PM0.1.
2. Kills 99.9% of harmful bacteria and viruses
Air purifiers have the ability to eliminate 99.9% of H5N1 viruses in the air and 96.5% in solution through Plasmacluster ion technology, a standout feature of Sharp air purifiers. This technology is particularly safe for users as it does not emit any harmful chemicals.
Plasmacluster ion technology releases Plasma molecules into the air to release positive and negative ions, forming hydroxyl radicals. These radicals attract hydrogen on the surface of bacteria and viruses, breaking them down and preventing their proliferation.

3. Eliminates mold and allergens
Air purifiers quickly eliminate pollen, pet dander... So, if anyone in your family is allergic to these factors, why hesitate to get an air purifier? With standard filters and advanced filtration technology, it can remove up to 99.97% of allergens and mold.
4. Effective Odor Removal
Food odors, cigarette smoke, tobacco smoke, harmful dust smoke... are odors that are harmful to health and difficult to remove, especially in greenhouse spaces or air-conditioned rooms.
Therefore, air purifiers will quickly eliminate unpleasant odors. Equipped with activated carbon filters and ion dispersion technology, the air in the room is cleaner and fresher.
5. Smart Convenience
In addition to purifying the air, killing bacteria, removing harmful substances, and deodorizing, air purifiers are also integrated with many smart features to provide users with more convenience and safety.
Some additional features equipped on air purifiers include humidifying the air, UV light disinfection, negative ion disinfection, remote control, smartphone control...

Should You Leave the Air Purifier On All Day?
The answer is no, you shouldn't leave the air purifier on all day because of the following reasons:
- Air purifier filters have a fixed operating hours. Therefore, running the purifier beyond optimal time (8 hours/day) will cause accumulation of dirt inside the filter, obstructing airflow.
- To maintain the purifier's initial effectiveness, the fan must increase power to counteract filter blockage. As a result, the fan becomes louder, consumes more electricity, wears out faster, and the filter quickly reaches its design lifespan, requiring replacement.
- Currently, air purifiers are equipped with negative ion systems to keep the air clean and fresh. However, maintaining the emission of negative ions for prolonged periods will generate high concentrations of negative ions, producing ozone with a pungent odor and adverse health effects with prolonged use.
Above, we've analyzed the issue of whether to buy an air purifier. We hope this information will help you better understand air purifiers and quickly purchase one for your family to create a clean and ventilated environment.
