UV air purifiers target or “inactivate” airborne microorganisms using ultraviolet light waves. Pathogens and UV light are both imperceptible to the naked eye. It may appear minor, yet it has far-reaching consequences. Air filtration is beneficial to one’s health and performing one’s heating, ventilation, and air conditioning (HVAC) system.
Short-wave ultraviolet light (UV-C light) is used in pure UV light air purifiers to inactivate airborne diseases and microorganisms such as mold, bacteria, and viruses. All air purifiers have the same end goal: to decrease indoor air contaminants. UV germicidal irradiation, or UVGI air purifiers, is another name for the technique. This is in contrast to other air purifier technologies that employ UV light but do not use it to combat active air contaminants.
For What Purpose Do You Need An Air Purifier?
Indoor air can be filthy and full of triggering particles like pollen and dust, thus air purifiers are the best method to clean it. They also help to keep the environment healthy by eliminating:
- Pet dander
- Mold spores
- Other contaminants.
Some models are created with a specific purpose in mind:
If you have allergies, choose an allergy-friendly air purifier. To eliminate indoor allergens, they usually include many filters, including HEPA filters.
If you have asthma or if odor and chemical pollutants aggravate your symptoms, consider an asthma air purifier or an odor and chemical air purifier. These also contain added odor and chemical filtration.
These air purifiers are designed for removing:
- Fireplace soot
- Other associated fumes
These could aggravate existing respiratory conditions or cause unpleasant odors in your environment.
Select the air purifier that is designed for handling pets. They are used to removing:
- Pet dander
If you have multiple chemical sensitivities and are extremely sensitive to chemicals, consider an air purifier. These models have even more odor and chemical filtration, and they’re often made of materials that don’t release chemicals into the air, aggravating your symptoms.
The size of the Air Purifier:
Consider the square footage of the room you wish to filter when choosing the proper size air purifier for your needs.
If you have allergies or asthma and are looking for an air purifier to help control your symptoms, the air change per hour rate should be considered. The number of times an air purifier can filter the full volume of air in the treatment space, each hour is referred to as ACH.
Air purifiers that clean the air in the space at least four times per hour are the best for allergies and people living with asthma. The rate of four air changes per hour also ensures that the air purifier cleanses the air and filters out as many microscopic symptom-triggering allergens as possible to keep your breathing easy.
Air purifiers are sized for four air changes per hour as:
What Features Do You Need In An Air Purifier?
After choosing the size and type of the air purifier, you also need to consider some features. These features include:
- Look for energy-star rated to save money and conserve energy.
- You can also find Wi-Fi air purifiers that are controlled by phone.
- Indicators should give real-time updates on the quality of the air.
Other features include:
- Caster wheels
- Handles for easy mobility
- Remote controls
- Multiple fan speeds
- Filter change indicators.
Where to Place Air Purifier?
In many situations, it is essential to place the air purifier in the room, as most of the time is spent there. It is recommended to place the best UV air purifier for viruses in the room.
Keep in mind that portable air purifiers are only meant to filter the air in one area, so you may need to purchase extra units to clean the air in other rooms. Alternatively, you may select a unit with caster wheels, handles, and other mobility features to make moving it from room to room easier.
Whole-house air purifiers are becoming increasingly popular to ensure clean air in all of your rooms. As you heat, chill, or ventilate your house, these devices connect to your current HVAC system to purify the air within.
How Often Should Air Purifiers Be Serviced?
The most common kind of air purifier maintenance is the replacement of air filters. When do you think you will need to replace them?
- HEPA Filters: Depending on usage, HEPA filters last roughly a year.
- Carbon Filters: Activated carbon filters have a six-month lifespan.
- Pre-Filters: Pre-filters typically last three months, although some are washable for longer filtering.
Other air purifiers, such as our Air Free air sterilizers, clean the air by using heat or UV light to destroy bacteria and allergies. These models never require filter change.
What is the process by which UV air purifiers purify the air?
UV-C light air purifiers function straightforwardly. As previously said, they employ UV lights that can change the DNA of microbes, rendering them inactive or dead. This light may be not visible to the naked eye, depending on the emitter’s substance. Mercury lamps emit UV-C light with a wavelength of 254 mm, which is commonly used in residential apartments.
UV light air purifiers often combine a forced-air system with another filter. As a result, the air purifier’s UV light works in tandem with other processes to purify the air. The ambient, in-house air is pushed through the device and vented through a chamber with lamps that emit UV-C light. In a portable air purifier, the UV light is positioned after the filter. The type of UV lamp, humidity, and temperature can all affect its performance.
UV-C germicidal purifier lamps are silent, and the brightness of many is undetectable to the naked eye, depending on the casing put around it. They usually have no odor. Depending on the brand and type, UV bulbs may need to be replaced once a year.
What is the efficacy of UV air purifiers?
While UV-C radiation can kill microorganisms, whether it can do so in a portable air purifier machine is another story. These devices are frequently touted as having the ability to decrease dust mites and mold allergies.
The effectiveness of UV-C light in disinfecting the air is determined by several factors, including:
- Whether the pollutants come into contact with the light
- Whether the light is inhibited by the cooling effect of airflow
- The material of the bulb emitting such light
- A high dosage of light is required.
- How long the pollutant is exposed to the light.
Benefits of the Air Purifier:
- The purifiers of the air asthma triggers are removed
- Allergens such as dust and pet odor are removed by air purifiers.
- Purifiers of the air preventing lung disease by trapping tobacco and cigarette smoke
- Purifiers of the air remove asbestos particles from the air, lowering the risk of mesothelioma
- Purifiers of the air radon gas is a carcinogen that can cause lung cancer.
- Purifiers of the air remove pollutants and outside fumes from urban environments.
- Air purifiers of the air should be reduced. This reduces the risk of developing leukemia and lymphoma by eliminating volatile organic compounds (VOC).
- Purifiers of the air prevent malaria infections by removing potentially dangerous insects.
