HIGH-EFFICIENCY FILTRATION

Because What You Cannot See Still Matters.

Cleaner air starts with effective filtration, because the particles you worry about are not always the ones you can see. PURIFINA's filtration system features a HEPA H13 filter, designed to capture up to 99.97% of particles at 0.3 microns as air passes through the filtration system, helping reduce dust and fine airborne particles circulating within your space. Thoughtful filtration working quietly in the background, for cleaner air throughout your everyday environment.

HEPA H130.3 micron particlesUp to 99.97%

The 99.97% figure is the capture efficiency measured at the filter, not a measurement of a whole room. Real results depend on room size, running time and the surrounding air.

MULTI-LAYER FILTRATION

Layer by Layer. Cleaner by Design.

Cleaner air comes from more than one layer of care. The PURIFINA multi-layer filtration system is designed to address different types of airborne impurities at different stages, from larger particles to fine particles and unwanted odors. Each layer has a role. Together, they create a more complete approach to everyday air purification.

Different layers. One purpose: cleaner air.

UV-C TECHNOLOGY — SELECTED MODELS

An Extra Layer of Air Care.

For those looking for an additional level of air care, selected PURIFINA models combine the filtration system with built-in UV-C Technology. Working alongside filtration, UV-C adds another technology to the purification process, giving you more choice in how you care for the air in your space.

More than filtration. An extra layer of air care.

UV-C TechnologyWorks alongside filtrationProduces no ozone

Available on the P402-UV and P302-UV only. The UV-C lamp works at the filter inside the unit. Its 9,000-hour service life depends on actual running time, and a reminder light tells you when it is due for replacement.

REAL-TIME AIR QUALITY DISPLAY

See the Air Around You.

Air may be invisible, but its condition does not have to be. The built-in air quality monitoring system detects PM2.5 and displays real-time information, helping you understand the air around you at a glance. No guessing. Just clearer information to help you feel more in control of your everyday environment.

Frequently asked questions

What size room needs which model
The catalogue prints a room size for every model, so use that. P501 covers 50 to 70 sq m (CADR 580) · P402-UV 35 to 60 (CADR 420) · P401 28 to 48 (CADR 400) · P412 45 (CADR 350) · P302-UV 20 to 30 (CADR 220) · P301 17 to 30 (CADR 200) · P201 24 (CADR 187). CADR is how much clean air the unit puts out an hour, so the higher it is the bigger the room it clears. If your room falls between two models, take the larger one and run it on a low setting, which is quieter anyway.
What does the UV-C version add
A UV-C lamp at the filter, which the catalogue says raises its effectiveness against germs, bacteria and mould on the filter, and produces no ozone. The lamp is rated for 9,000 hours, depending on how much you run it. Two models have it, P402-UV and P302-UV, and both also time up to 16 hours where the others manage 8. If you do not need UV-C, P501 and P412 add an antibacteria layer on the filter instead.
How do I change the filter, what does it cost
Every model has a filter change light on the unit, so there is no counting days. P401 also has a filter cleaning reminder on top of that. All filters are HEPA H13 and are ordered by code: FHC-P201 at THB 790.- · FHC-P301 THB 1,290.- · FHC-P412 THB 1,590.- · FHC-P302 THB 1,990.- · FHC-P401 THB 1,990.- · FHC-P402 THB 2,390.- · FHC-P501 THB 2,390.-. The catalogue does not say how many months a filter lasts, so go by the light and the manual.
How long is the warranty, who do I call
The catalogue prints a two year warranty in the UV-C block, covering P402-UV and P302-UV. For the rest, no warranty terms are printed on the same page, so we will not quote a figure here. Ask a service centre or the dealer about the model you have in mind before you buy. Call us either way. MEX has service centres nationwide on 02-493-6565, with people who can help on room size, choosing a model, and ordering replacement filters.
