(NEW) FrostWash 3.0 self-cleaning process

airHome 800_1

(NEW) FrostWash 3.0 self-cleaning process

A new & more complete self-cleaning process for the heat exchanger coil! FrostWash 3.0 heats up the coil up to 56˚C before freezing and melting it. This way, it detaches oily particles and odor sources in addition to other dirt and contaminants.

Triple effect of FrostWash 3.0:

  1. Sanitizing effects: 99% viruses eliminated [1], 99% bacteria eliminated [2], 95% mold reduction[3]

  2. Anti-odor effect: In addition to removing mold, a common source of bad odors, FrostWash 3.0 significantly removes bad smells that may have adhered to the surface of the heat exchanger, such as pet odors [4] and cooking odors [5].

  3. Preservation of airflow capacity: Our tests show that systems with FrostWash are 3×better at maintaining airflow performance than those without this technology[6] .

*FrostWash 3.0 does not work when airHome 800 indoor unit is connected to airHome Multi/Multi Pro outdoor unit. In such case, the FrostWash 3.0 is substituted by standard FrostWash – freeze/melt/clean – process.

(NEW) Smart Mold guard 2.0

airHome 800_1

(NEW) Smart Mold guard 2.0

With its embedded sensors, the Mold Guard 2.0 continuously monitor the temperature and humidity levels inside the indoor unit, even when the units is turned off. ​
When it detects conditions that favor mold growth inside the AC (ie humidity levels above 65% and mild temperature), automatic mold killing process is activated:​

Process to kill inside mold:​

  • Heat exchanger’s coil heated at up to 50ºC

  • Air is circulated within the interior of the unit​

  • As a result, the humidity levels of the unit’s interior will dramatically reduce, below 30% and the inside temperature will reach up to 45ºC, in order to kill mold in less than 10min.​

AQtiv-Ion against viruses, bacteria and allergens

airHome 800_1

AQtiv-Ion against viruses, bacteria and allergens

An exclusive technology contributing to building a healthier environment! When AQtiv-Ion is activated, the AC emits negatively-charged particles which cling to pollutants in the air around the AC unit, so they fall harmlessly to the ground.​

Tested and proven:​

  • 99.9% inhibition of viruses: tested on SARS-CoV-2 [8] & Hong Kong Influenza A (H3N2) ​

  • 99.0% reduction of bacteria: tested on E.Coli [9]

  • 86.0% reduction of formaldehyde [10], a common source of bad odors​

  • 97.1% reduction of cedar allergens [11] and 98.7% against dust mites [12 ]

The AQtiv-Ion technology can be used anytime during cooling, heating, dry and fan mode, to purify your air regardless of temperature control.

ViroSense Z1 air purifying filter

ViroSense Z1 air purifying filter
