Overview

SilverOnyx is a company that specializes in designing healthy living products such as vacuums, scales, vitamins, and air purifiers. 

The SilverOnyx air purifier was chosen as the top air purifier for bacteria and viruses because of its unique design and a 5 stage purification process. The purification process includes a 360 degree pre-filter, True HEPA filter, and Activated Carbon Filter, and also has an ionizer and UV-C sterilizer.

The SilverOnyx features a five stage filtration process, five fan speeds, easy-to-use push button display, sleep function to turn off lights, particulate matter sensor that automatically adjusts airflow, on/off timer, filter change light indicator, auto mode, quiet performance, and a lightweight design. 

The product’s 360 degree design takes up less space than flat filter purifiers while still allowing for 60% more surface area. This is why the SilverOnyx is able to filter more cubic meters of air per minute.

As bacteria, viruses, germs, and more flow into the purifier, they first flow through a mesh pre-filter that captures large particles, the air then enters the true HEPA filter that removes 99.97% of particles and odors under .3 microns in size. After syphoning through the HEPA filter, the dirty air reaches the activated carbon filter. The carbon filter uses millions of crushed charcoal particles to absorb odors and small particles. After flowing through the activated carbon filter, the air contaminants enter the UV-C chamber which zaps and kills any mold, germs, bacteria, viruses or living organisms with intense UV light. The final stage in the purification process (if turned on) is for any remaining dirty air to pass through the ionizer.  

As you can see, the Silver Onyx’s advanced purification process combined with the increased level of surface area due to its 360 degree design is the reason for purifier being the best on the market. Bacteria and viruses are eliminated from the HEPA and UV technologies while other contaminants are removed from the pre-filter, HEPA filter, Carbon filter, and ionizer.

Why use an Air Purifier for Bacteria and Viruses?

When someone coughs or sneezes they release thousands of micro-organisms into the air.  These micro-organisms are often filled with bacteria and viruses called germs. When exposed to people, germs can cause colds, flus, and viruses. 

Sneezes can travel at speeds up to 100 miles per hour and can reach distances of 3 meters! Also, bacteria and viruses released from a cough or sneeze will subsequently linger in the air before falling onto surrounding surfaces.

This is why it is important to use an air purifier to draw in and destroy these germs before they have a chance to be inhaled or contaminate surfaces in the area.  

Which Air Purifiers are Best for Bacteria, Viruses, and Germs

When looking for the best air purifier for bacteria and viruses it is important to make sure that the purifier features ultraviolet light technology and a HEPA filter. These two technologies will be vital to capturing and killing air contaminants of this type.

UV-C light technology will kill bacteria and living organisms as they pass through the purifier, while HEPA will trap 99.97% of contaminants that are at least .3 microns in size. To put that into prospective, the diameter of a single human hair is around .7 microns in size. 

The combination of these two types of technology will provide the best solution for eliminating germs, bacteria, and viruses. 

Benefits of Air Purifiers that Kill Germs

  • Kill airborne pathogens
  • Reduce spreading of the Flu, colds, and more
  • Reduce airborne bacterial counts
  • Improve overall air quality
  • Prevent the spreading of viruses
  • Eliminate the growth of fungi

What is ultraviolet (UV) light?

UV rays are a form electromagnetic radiation that is commonly known as light. Light travels in waves, and each form of light has a different wavelength. The wavelength of UV rays are too small for the human eye.

You’ve probably heard of UV rays when watching the weather channel in the summer because of their damage to human skin. The sun produces three forms of UV light that can be harmful to human skin. The forms of UV light are UV-A, UV-B, and UV-C rays.

How Ultraviolet Light (UV) Technology Kills Germs

An ultraviolet light air purifier uses a UV-C light chamber to burn and subsequently kill living organisms at the particulate level. As air is drawn into the purifier, it will be directed into the UV-C chamber. Intense levels of UV light (the same light that gives you a sunburn in the summer) are exposed to the contaminants. These intense levels of light will kill bacteria and viruses. Basically, the viruses and bacteria are sent through an intense tanning bed.
