Frequently Asked Questions - AC 37 HCICH Tesy

How do I replace the HEPA filter on my Tesy AC 37 HCICH air purifier?

To replace the HEPA filter, first unplug the unit. Open the front cover by pulling it towards you. Remove the old filter and insert the new one with the arrow pointing upwards. Close the cover and plug back in. Reset the filter indicator by holding the timer button for 3 seconds.

What is the recommended filter replacement schedule?

The pre-filter should be cleaned every 2 weeks with a vacuum cleaner. The HEPA and activated carbon filters should be replaced every 6 to 12 months depending on air quality and usage. The filter replacement indicator will alert you when it's time.

Can I use the air purifier 24/7?

Yes, the Tesy AC 37 HCICH is designed for continuous operation. It has an auto mode that adjusts fan speed based on air quality, and a sleep mode for quiet nighttime use. However, it is recommended to turn it off occasionally for maintenance.

What room size is this air purifier suitable for?

The Tesy AC 37 HCICH is effective for rooms up to 40 m² (approx. 430 sq ft). For larger spaces, performance may decrease. It can achieve up to 200 m³/h CADR.

How do I clean the pre-filter?

Unplug the unit and remove the front cover. Take out the pre-filter (the outer mesh). Use a vacuum cleaner with a brush attachment to gently clean both sides. If heavily soiled, wash with water and let it dry completely before reinstalling. Do not put in dishwasher.

Does the air purifier produce ozone?

No, the Tesy AC 37 HCICH uses HEPA filtration and UV-C light but does not include an ionizer. Therefore, it does not produce ozone, making it safe for people with respiratory issues.

What does the UV-C light do?

The UV-C light helps kill bacteria, viruses, and mold spores that pass through the filter. It works in conjunction with the HEPA filter to provide an additional layer of air purification, especially for microorganisms.

How noisy is the air purifier?

The noise level varies by fan speed: Low (≈30 dB), Medium (≈40 dB), and High (≤45 dB). Sleep mode runs at the lowest speed for quiet operation. It is suitable for bedrooms.

How do I reset the filter replacement indicator?

After replacing the filters, plug the unit in and press and hold the Timer button for 3 seconds until the filter indicator light turns off. This resets the timer for the next replacement cycle.

Can I use the air purifier with windows open?

It is more effective with windows closed to recirculate and clean the indoor air. Open windows introduce outdoor pollutants, making it harder for the purifier to maintain clean air. However, occasional ventilation is still recommended.
