AP4 Air Purifier & Humidifier

The AP4 is a combined air purifier and humidifier designed for spaces that require both consistently clean air and balanced humidity levels. Its intelligent control system continuously monitors indoor air quality and adjusts purification and moisture output based on real-time PM2.5 data and ambient conditions. The AP4 supports everyday comfort, seasonal humidity control, and longterm
wellbeing in homes and offices.

Multiple Operating Modes

The device offers Automatic, Manual, Night, and Timer modes, allowing operation to be precisely tailored to current needs and environmental conditions.

Negative Ion Function

The built-in ion generator releases negative ions that help reduce airborne pollutants and enhance the overall freshness of the air.

Light Sensor

Under low ambient light conditions (below approximately 5 lux), the display brightness is automatically reduced and the unit switches to Night Mode for undisturbed rest.

Remote Control

Allows convenient and effortless operation from a distance.

Wi-Fi Connectivity & App Control

Enables remote monitoring, scheduling, and real-time air quality tracking via a mobile application.

Child Lock

Prevents accidental or unintended changes to settings.

Filter Replacement Indicator

Notifies the user when filter replacement is required.

Eight Fan Speed Levels

The fan can be adjusted across eight manual speed levels or operated in automatic mode, ensuring optimal airflow at all times.

Integrated Humidifier

Maintains optimal indoor humidity levels while seamlessly supporting the air purification process.

7-Stage Filtration System

A multi-layer filtration system that effectively removes airborne pollutants, from large particles to microscopic contaminants.

7-Stage Filtration System

The Richter AP4 is equipped with a multi-layer, combined 7-stage filtration system designed to effectively reduce airborne pollutants, from larger dust particles to fine, invisible contaminants.

The Pre-Filter

Made from aluminium alloy, this washable primary filter captures larger particles above 5 microns, such as dust, hair and lint. Reusable multiple
times.

Cold Catalyst Filter

Helps break down residual gases and low-concentration chemical pollutants commonly found in indoor environments.

Cellular-Activated Carbon Filter

Adsorbs volatile organic compounds (VOCs), household chemical fumes and unwanted odours.

Antibacterial Cotton Layer

This filtration stage is captures fine particles around 5 microns and incorporates an antibacterial agent that eliminates more than 99% of airborne bacteria.

High-Efficiency HEPA Filter

Removes fine particulate matter down to 0.3 microns, including PM2.5, pollen, mould spores, dust, allergens and certain viruses.

UV-C Sterilization

The UV-C light (365 nm) helps reduce airborne bacteria and viruses by inactivating
bacteria and viruses.

Anion Purifier

Releases negative ions that bind to ultrafine particles, causing them to settle more quickly and enhancing the overall feeling of air freshness.

Built-In Humidifier

• Integrated humidification with a dedicated filter
• Operates with standard tap water and automatically produces humidity once filled
• Humidity output adjusts according to the selected fan speed
• Water-level indicator signals when refilling is needed.
