Filtration Technology

The MERONTE uses a True HEPA filter that captures 99.97% of airborne particles as small as 0.3 microns, including dust, pollen, pet dander, and other common impurities. While it handles particulate matter well, it does not include a dedicated activated carbon stage for gas-phase pollutants or strong odors.

For light smoke and everyday freshness, the built-in fragrance sponge can help mask mild odors, but heavy smoke or chemical fumes are better addressed by purifiers with thick carbon filters.

Noise & Performance

At just 22 dB on its lowest setting and 23 dB at maximum, the MERONTE is remarkably quiet , quieter than a library and virtually inaudible during sleep.

FAQ

How quiet is the MERONTE air purifier for sleeping?

At 22 dB on its lowest setting, this purifier is quieter than a soft whisper and virtually inaudible. Even at max speed it only reaches 23 dB, so it won't disturb light sleepers.

The dedicated sleep mode also dims the display for a darker bedroom.

Does this air purifier remove pet dander and pet odors?

The True HEPA filter captures 99.97% of particles at 0.3 microns, which includes pet dander and fine pet hair floating in the air. For mild pet odors, the fragrance sponge can help freshen the room, but it lacks a dedicated carbon filter for heavy odor absorption.

How often do I need to replace the filter on the MERONTE purifier?

MERONTE recommends filter replacement every 3 months. The built-in filter change indicator light will alert you when it is time, so you don't have to guess.

Replacement frequency may vary depending on air quality and how many hours per day you run the unit.

What size room does the MERONTE air purifier cover?

It covers rooms up to 225 sq ft, which fits most bedrooms, home offices, and nurseries. For larger spaces like open-plan living rooms, you would need a higher-capacity unit or multiple purifiers to maintain effective air quality.

Can I use essential oils with this air purifier?

Yes, the MERONTE includes a built-in fragrance sponge designed for essential oils. You add a few drops to the sponge, and the purifier disperses the scent as it circulates air.

This eliminates the need for a separate diffuser on your nightstand.

Does this purifier work with Alexa or a phone app?

No, the MERONTE is a manual-control purifier with no WiFi, app, or voice assistant integration. All settings , fan speed, sleep mode, and the night light , are controlled directly on the unit.

If smart home integration is a priority, you will need to look at WiFi-enabled models.
