^ Replacement filters/ estimated cost
At around 40+ for a single unit Clarifion GL-139, it is well worth the price considering its offering. The compact form is best suited for the bedroom, bathroom, hallway, kitchen, living room, staircase, office, and garage use. Another good thing about Negative Ion Generator is it does not need replacing. No expensive filtration or light bulb changes for the rest of the ownership. Still, you will need multiple units to cover the entire home due to the limited purifying coverage.
Clarifion GL-139 Negative Ion Generator is available for purchase at Amazon and the official website. Both sites offered discounted prices with great bundled deals if you buy more than 1 unit. You can see significant savings with at least a 4-in-1 bundled deal. For the first time buyer, we would advise our reader to go with a single unit first as a trial. Test it out and if they are happy with the purchase, opt for the greater bundled deal.

Clarifion GL-139 VS the challengers

GermGuardian GG1100W Elite Pluggable UV-C Sanitizer

GermGuardian GG1100W/ GG1100B

A pluggable air sanitizer that uses UV-light filtration to clean the air rather than an ionizer. Ultraviolet light is more effective in killing bacteria and viruses but you will have to replace the light bulb regularly.
GermGuardian GG1000 Pluggable Air Purifier & Sanitizer

GermGuardian GG1000 Pluggable

The older version to GG1100 and it is roughly the same price as Clarion. Go with this if you prefer UV-light over negative ion generator.
