FAQ

Why Choose 2-in-1 Purify + Humidify?

Staying comfortable year-round means keeping humidity between 40–60%. When humidity climbs above 70%, it can create the perfect environment for mold, dust mites, and bacteria.

This 2-in-1 unit takes care of both air quality and moisture. The lower unit captures airborne particles, while the upper unit adds clean, refreshing humidity.

Questions & Answers

Before you buy — common questions.

The device can cover areas ranging from 150 - 1200 ft². It is suitable for large rooms up to 1200 ft², making it ideal for spaces like living rooms, as well as smaller areas such as bedrooms and offices within its lower coverage range.

Yes, the humidifier module is detachable. This allows users to use the air purifier alone when the humidification function is not needed.

The water tank capacity is 1.5L (3.2 Pint). This provides continuous humidification, reducing the frequency of refilling.

Yes, it has a whisper-quiet sleep mode. In this mode, the device operates at a low noise level of 24dB, and the display light can be turned off, creating a peaceful and undisturbed sleep environment.

We recommend replacing the air filter every 6 to 8 months and the humidifier filter every 6 months for optimal performance. Clean the humidifier filter with water weekly and replace it if it appears yellow or moldy.
