Unlike HEPA filters which is just a filter, TPA destroys particles. To eliminate bacteria and pathogens, the device uses charged ions. Even the smallest particles that could trigger allergic reactions like asthma can be captured. You can click on the link to browse more: https://airdogusa.com/pages/benefits-of-air-purifiers

If you have asthma or allergies, an air purifier can help you get rid of the sneezing, coughing, runny nose, and itchy eyes that are brought on by allergens and other irritants in the air. Air purifiers can make it simpler for you to breathe and improve your quality of sleep by removing these irritants from the air.

Yes, he can remove particles from 0.0146 microns to PM 2.5 (such as dust and pet dander), and larger particles (such as pollen and pet hair). See more on this page: https://airdogusa.com/pages/benefits-of-air-purifiers

Airdog X5 uses an advanced electronic design built around safety. The power consumption of Airdog is equivalent to a small light bulb. It has high voltage inside but very low current in the order of micro-amps. The high voltage runs on direct current to avoid any possible electronic perturbation.

We designed and manufactured Airdog X5 complying to Energy Star Rating. We are on our way to obtaining the certificate. Airdog X5 is an Eco-friendly product because it uses non-consumable collecting plates instead of producing fiberglass waste, which is the main material of HEPA, and others.

Airdog X5 is a cost effective and environmental green solution.

A. Collecting plates in Airdog X5 is washable and reusable, so no more spending on HEPA filters and others.
B. Composite catalyst gauze is reusable, you may put it directly under the sunlight for 1~2 hours to refresh it. However, some customers might be very sensitive to any smell and might have to change the composite catalyst layer every 6-24 months to refresh the smell. The cost of the catalyst layer is only a small fraction of the cost of HEPA. To replace the catalyst layer, please contact your sales resource where you bought Airdog X5.

The best part of Airdog X5 air purifier is that you could see the effect by your own eyes! You will notice the AQI (Air Quality Index) number decreasing when the air purifier is on. Also, after using X5 for a week, you can actually see many of the pollutants absorbed on the collecting plates when you take the plates out of X5 to clean.

The number displayed on Airdog is called Air Quality Index (AQI). It was developed by the United States Environmental Protection Agency (EPA) to report air quality. The AQI is divided into six categories, indicating increasing levels of health concern. The displayed AQI on Airdog X5 is calculated based on the infrared sensor embedded in the unit, which measures the number of particles in a restricted air volume. This number can fluctuate according to the air flow velocity, position and ambient air condition. Thus it is a good reference for you to know the ambient indoor air quality.

Display of “-C-” means it is time to do a cleaning. The “9XX” is an electronics abnormal signal. Please unplug the unit and do a full clean cycle and restart. If the “9XX” still exists, please contact customer service for further instructions.

The dust accumulated on the sensor could cause insensitivity of sensors. Please clean the sensor with a dry cloth or a cotton swab with alcohol.

The occasional “zapping” or “cracking” is normal when the bigger particles enter the air purifier, being zapped by the high voltage, similar to when a bug zapper traps a bug. However, if the “cracking” or “zapping” noise is constant, you should clean the unit and make sure that all parts in the unit are fully dried after you clean the unit. 80% of the noise issues are caused by dust accumulation on the collecting plates and/or inner chamber, or by wet collecting plates. Normally a full clean cycle will take care of this all.

A. When “-C-” is on the display screen.
B. “9XX” appears on the display screen even after cleaning the collecting plates.
C. Cracking sounds still exist after cleaning the collecting plates.
D. The unit shuts down and restarts automatically. Note: Please refer to the “Full cleaning cycle” section in the user manual for details.

You should not put the whole Airdog X5 unit into the dishwasher! Only the collecting plates is OK to be washed by a full wash cycle. Please make sure the collecting plates unit is fully dried before putting it back into your Airdog X5. There could be water residue inside of the collecting plates even after the drying cycle sometimes, so make sure to take the time to fully dry them.

Please put the collecting plates in a dry space for at least 24 hrs. You may put tissues or a paper towel under the collecting plates to check if it is fully dried.

A. Please make sure that all parts are dried fully.
B. Please make sure that the contact pin goes through the small hole in the rubber sleeve (as shown in pictures below) when you are assembling the unit. (Contact pin is exposed after taking out the generating electrode.)

Press and hold" Reset" on Remote Control for 6 seconds.

A. Airdog App does not support IPv6 network environment.
B. Make sure your Wi-Fi is in 2.4GHz.
C. The home Wi-Fi environment could be complicated. To verify if the smart control system is functional or not, you could use the hotspot on another phone instead of the home Wi-Fi to make a connection. The hotspot could simplify connection complexity and verify the hardware function.
D. We have finished the App and server migration. Please double check the label on the back of the unit, if it is a green matrix code, you are good to download the “Airdog Pro”App and connect. If it is a blue matrix code, please check whether your firmware is upgraded or not.
