Frequently asked questions

Questions we are often asked

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.
