Questions and answers

Which is better for a family of four?
The GlacierFresh, because its 3-gallon total capacity holds more water between refills. The Culligan holds 2.25 gallons.
Which lasts longer between filter changes?
The Culligan. Its filter is rated for 6 months; the GlacierFresh filter is rated for about 3 months or 200 gallons.
Is the GlacierFresh worth the extra $10?
Yes if you want more capacity, a filter-life display and fluoride and heavy-metal reduction claims. If you mainly want low running costs, the Culligan wins on filter life.
Do either need electricity or plumbing?
No. Both are gravity-fed countertop units that work during power outages.
Which removes more contaminants?
On paper, the GlacierFresh, which claims multi-stage reduction of fluoride, heavy metals, microplastics and chlorine with NSF 42/53/401/372 claims. The Culligan lists ceramic and granular activated carbon only.
Will either fit under a cabinet?
Check height first. The Culligan is 26 inches tall. The GlacierFresh is 13.58 inches wide, and buyers report its lid knob sits about 5mm higher than expected.
