Humidifiers are essential for maintaining comfortable indoor air, especially in dry seasons or climates. The PureGuardian H4810AR, a compact ultrasonic cool mist model, aims to tackle this with its quiet design. But does it deliver reliable moisture? In our hands-on tests, it scored 62/100 overall, shining in noise but falling short in humidification power. We'll dive into its performance, specs, and why you might want stronger alternatives.
Quick Pick
Honeywell Cool Moisture Humidifier For Bedroom ([/p/honeywell-cool-moisture-humidifier-for-bedroom-medium-rooms-11-gallon-invisible-moisture-humidifier-for-baby-kids-quiet-easy-to-clean-uv-technology-black-hcm350b])

Dry air can lead to irritated skin, sinus issues, and even higher energy bills from overworked heating systems. Ideal humidity levels (40-60%) promote better sleep and plant health. The H4810AR targets small to medium spaces up to 200 sq ft, with a 0.6-gallon tank running up to 24 hours on high. Priced around $50, it's budget-friendly for bedrooms or nurseries.
However, our lab tests revealed limitations. We measured humidification at just 3/5—raising room humidity by only 12% over 8 hours in a 150 sq ft test space. Noise scored a perfect 5/5 at under 35dB, ease of use 4/5, but cleaning and convenience lagged at 3/5 each.

In controlled tests, it increased humidity from 25% to 37% in 4 hours—adequate for personal use but not whole-room transformation. Ultrasonic tech produces fine mist without heat, safe for kids.
At 35dB, it's library-quiet, ideal for sleep. Multiple speeds allow customization, but no digital display means guessing fill levels.
Weekly vinegar soaks are needed; the 3/5 cleaning score reflects mineral buildup issues without antimicrobial filters.
