When it comes to air purifiers, there are two main types: those with filters and those without. Unfiltered air purifiers can cover a larger area of up to 3,500 square feet, while filter purifiers cover about 1,000 square feet of space. But is an air purifier without a filter really a good option? Let's take a look at the pros and cons of these devices.The main advantage of an air purifier without a filter is that it can save you money in the long run. You won't have to buy tons of supplies such as air filters, sterilizers, disinfectants and other cleaning products.
However, you should evaluate the air change rate per hour (ACH) of the purifier to determine how quickly it purifies given the square feet of space.One type of air purifier without a filter is the UV air purifier. These devices use UV lamps to alter the DNA of microorganisms and inactivate or eliminate them. However, they may need bulb changes and some may need sterilization from time to time.Another type of air purifier without a filter is the electrostatic plate purifier. Instead of using a paper filter that easily clogs like most other air purifiers, these devices come with an electrostatic plate that picks up particles in the air.Finally, there are also pluggable Germ Guardian purifiers that use UV C light to kill bacteria in the air.
The exact dimensions of these units are 8.5 x 8.5 x 10.4 inches, which places them around the same size as the Airfree Lotus air purifier.The main disadvantage of an air purifier without a filter is that it may not be as effective as one with a filter. For example, if you suffer from allergies or asthma, you should opt for an air cleaner that provides clean air at least four times an hour. Additionally, some models may not be as effective in removing particles from the air as those with filters.Another disadvantage is that some models may be hazardous to your health if they don't work properly. For example, ultraviolet light is a powerful cleaning agent that kills microorganisms such as mold and bacteria in the air.
However, actual results may vary and may be affected by variables such as ventilation, natural airflow, and humidity levels.Finally, there are also TSS core technology units that heat the unit's air and cool it before releasing it back to the atmosphere. This type of unit effectively cleans air without the use of filters or a fan.In conclusion, an air purifier without a filter can be beneficial in some cases. However, you should consider all factors before making your decision. Evaluate the ACH rate of the device and make sure it meets your needs before purchasing it.
Additionally, consider whether or not you need a filter-based model for better results.
