Frequently Asked Questions - X-3500 XPower
How often should I clean or replace the HEPA filter?
The HEPA filter should be cleaned every 2-3 months with a vacuum or soft brush, and replaced every 6-12 months depending on usage and air quality.
How do I reset the filter replacement indicator?
After changing the filter, press and hold the filter reset button for 3 seconds until the indicator light goes off. This resets the timer for the next replacement cycle.
What is the recommended room size for the X-3500?
The device effectively purifies rooms up to 430 square feet (40 m²). For optimal performance, place it in a closed room of that size or smaller.
Can this air purifier help with allergies and asthma?
Yes, the HEPA H13 filter captures 99.97% of airborne particles such as pollen, dust mites, and pet dander, which can reduce allergy triggers and improve indoor air quality.
How do I use the timer function?
Press the Timer button to cycle through 1 to 8 hours. The device will automatically turn off after the set time. This is useful for saving energy while you sleep or when you are away.
What does Auto mode do?
In Auto mode, the air quality sensor monitors PM2.5 levels and automatically adjusts the fan speed. When air is polluted, the fan speeds up; when the air is clean, it slows down to save energy.
Is the air purifier quiet at night?
Yes, the sleep mode reduces the fan speed to its lowest setting and turns off the display lights, keeping noise levels as low as 25 dB, which is as quiet as a library.
What is CADR and why is it important?
CADR (Clean Air Delivery Rate) measures the volume of clean air produced per hour. A higher CADR means faster purification. The X-3500 has a CADR of 350 m³/h, suitable for medium-sized rooms.
How do I clean the exterior and the pre-filter?
Unplug the device and wipe the exterior with a soft dry cloth. For the pre-filter, remove the rear cover, take out the pre-filter, and vacuum it or rinse it with water. Let it dry completely before reinstalling.
What are the safety certifications and features?
The device complies with CE and RoHS standards. It includes a child lock to prevent accidental buttons, overheat protection, and a tip-over switch that shuts off if the unit is knocked over.
