Sanyawit: End-to-End Design, Installation, and Consulting for Clean-Air Systems in the Home
End-to-end design, installation, and consulting for clean-air systems. Because today's "air" is full of all kinds of contaminants — both visible and invisible — the first thing to consider in maintaining a good quality of life, free from disease and other disturbances, is the air around us: Is it clean enough? Is it genuinely safe from germs and air pollution?
To meet this need, Sanyawit offers end-to-end design, installation, and consulting for in-home air systems. Sanyawit's solution is an indoor air-quality management system that creates good-quality, clean, and safe air for the home. It works through our clean-air purification equipment such as the HCU, together with air-replenishment units such as the FAU, which draws good air into the home from the very first stage by creating Positive Pressure — so that stale air is pushed out through the various gaps in the house and outdoor pollution cannot enter. This working principle is different from that of ordinary air purifiers, ensuring that the air inside your home is of good quality — clean and genuinely safe from PM 2.5 dust as well as pathogens, bacteria, and various viruses.
Our services can be broken down into 3 main categories, as follows:

HEPA: Clean-Air Technology That Filters Contaminants Smaller Than 0.003 Microns
The HEPA filter in the HCU achieves a filtration grade as high as H14, a high level that is exceptionally well suited to aseptic rooms, with particle-capture performance down to 0.003 microns — a cleanliness rate of up to 99.999%. It also captures viruses, bacteria, mold, smoke, and droplets of every kind, protecting the health of those in healthcare facilities. It is considered the highest-performance filter in the field of air filtration.
In addition, the HCU air purifier delivers high airflow yet runs quietly at just 50 decibels, so it causes no disturbance and can be installed in a laboratory or a patient's room without disrupting rest. Every HCU unit has passed third-party hospital aseptic-room standard testing, so you can be confident in its performance — cleaning the air thoroughly and leaving no contaminants behind to trouble you.

Because airborne contaminants are far more delicate a matter than many people realize, and cannot be seen with the naked eye, having a means to control and screen out contaminants in healthcare facilities is an important consideration that should not be overlooked — for the safety of those receiving care and of the staff working in the facility.
