About TESSIO

TESSIO Smart Technology Co., Ltd. supplies household and health-focused electrical appliances under the TESSIO brand, from our office on Charoen Krung Road, Bang Kho Laem, Bangkok.

What we do

TESSIO focuses on the things a household touches every day: the air you breathe, the water you drink and the stove you cook on. Our range covers four groups — air purifiers, RO water purifiers, induction cooktops and stainless steel kitchen sets.

Why certification matters here

These products differ from ordinary goods in one important way: you cannot see whether they are working. You cannot tell by looking whether filtered water is genuinely clean, or how well the air leaving a purifier has been filtered. So we rely on third-party certification.

  • The RO membranes we use are certified to NSF/ANSI 58, the international standard for reverse-osmosis drinking water systems.
  • Our air purifiers are tested for electrical safety to IEC 60335-2-65 and IEC 60335-2-98 by SGS laboratories.

A registered company

TESSIO Smart Technology Co., Ltd. is registered as a juristic person under the Thai Civil and Commercial Code with the Department of Business Development, registration number 0105569131972, which customers are welcome to verify.

Ask us before you buy

An air purifier more powerful than you need will not make the air twice as clean — it will simply cost more. The same goes for cooktops: choose the wrong type and the pans you own may not work at all.

So please ask first. Tell us your room size, how many people live there, or send a photo of your kitchen counter, and we will help you compare models. Message @tessio369 on LINE or call 098-667-7205, Monday to Friday 9:00–18:00.

Frequently asked questions

Which air purifier suits my room size?
Start from the room area. For rooms up to 40 sqm such as a bedroom or condo, the K06A is enough. For 40–70 sqm living rooms or open areas, the K08D is the better fit. If you want one unit for the whole house, the A8 delivers a CADR of 760 m³/h. Not sure? Message @tessio369 with your room size.
How often do the filters need changing?
TESSIO air purifiers tell you when a filter is due. For RO water purifiers, sediment and carbon cartridges last roughly 6–12 months, the RO membrane 1–3 years, and post-carbon and alkaline filters about a year — depending on your water quality and usage.
Do the products come with a warranty?
TESSIO air purifiers carry a three-year warranty. For other product lines, ask about warranty terms on LINE at @tessio369 or call 098-667-7205 during office hours, Monday to Friday 9:00–18:00.
What standards do TESSIO RO purifiers meet?
Our RO membranes are certified to NSF/ANSI 58, the international standard for reverse-osmosis drinking water systems. Our air purifiers are tested for electrical safety to IEC 60335 by SGS laboratories.
What cookware works on an induction cooktop?
Induction zones need cookware containing iron — the quick test is to stick a magnet to the base; if it holds, it will work. The AT-999 also has an infrared centre zone that works with any cookware, including clay, glass and aluminium pans that magnets will not grip.
How do I order, and how is delivery handled?
Enquire and order on LINE at @tessio369, call 098-667-7205, or fill in the form on our contact page and our team will get back to you during office hours.
