GermGuardian AC4100 Review
The best travel-size air purifier is the $60 GermGuardian AC4100. This small table-top unit is capable of cleaning air in a room up to 120 square feet with its 3-stage filtration system that is just like the AC4825. The HEPA filter lasts up to 8 months and has a replacement cost of $22, while the UV light will last up to one year and can be replaced for $15.
The GermGuardian AC4100 has a rotary dial with 3 speed settings that are all very quiet. You can place it horizontally or vertically on a tabletop to suit your space.
