Our take on the GermGuardian AC4870 HEPA PURE 22" Tower Air Purifier

The GermGuardian AC4870 is a 22-inch tower air purifier with a 4-in-1 filtration stack: a pre-filter, a charcoal filter for odors, a true HEPA filter rated to capture 99.97% of particles down to 0.1 microns, and a UV-C light. It is rated for rooms up to 743 square feet and gives you five fan speeds, an 8-hour timer and a filter and bulb replacement indicator. It suits allergy sufferers and pet owners who want odor and particle control in a bedroom or living room. Against rivals it is a tall, lightweight tower with no oscillation and no remote, so it moves air in one direction and you set it by hand; the UV-C stage is a feature most competitors at this level leave out.

Pros

Cons
  • No oscillation, so airflow stays fixed

What reviewers say

Owners generally rate the AC4870 well for allergy relief and odor control, and many like the quiet low speed for bedrooms. Complaints center on the lack of oscillation and remote, filter and bulb replacement costs, and airflow that feels weaker on the highest setting than the size suggests.

What people mention
  • FiltrationPraisedOwners report less dust and fewer allergy symptoms with the HEPA stage running daily.
  • NoisePraisedThe low speed is described as quiet enough for a bedroom at night.
  • Odor controlPraisedThe charcoal layer is credited with reducing pet and cooking smells.
  • OscillationCriticisedReviewers note the fixed airflow does not sweep the room like oscillating rivals.
  • Remote controlCriticisedBuyers miss a remote and have to walk to the panel to change settings.
  • Upkeep costMixedFilter and UV-C bulb replacements are seen as necessary but an ongoing expense.

Questions and answers

How often do the filter and UV-C bulb need replacing?
GermGuardian lists the filter at every 6 to 8 months and the UV-C bulb at roughly once a year. The unit has separate indicators for both.
Which replacement filter fits the AC4870?
It uses Filter B, sold as FLT4825, FLT4825SM, FLT4825VO or FLT4850PT. The charcoal pre-filter is part of that filter assembly.
Is it loud enough to disturb sleep?
On the low speed it runs ultra-quiet, which is why owners use it in bedrooms. Higher speeds are noticeably louder.
Does it oscillate or come with a remote?
No. The AC4870 has no oscillation and no remote; all settings are on the digital control panel.
What room size does it handle?
It is rated for rooms up to 743 square feet. In a large or divided space, expect it to work best in the area it faces.
What is in the box?
The purifier, one filter set and one UV-C bulb, plus the digital controls and timer built into the unit.
