Do we use HEPA filters?

No, we don’t use HEPA filters. There are NO traditional filters inside Poiema U400.

Do we use carbon filters?

No, we don’t. Carbon filters are commonly used in filter-type air purifier. Their main function is to absorb VOCs (Volatile organic compounds). U400 uses TPA technology to decompose and remove VOCs directly, therefore you can be assured that the filtered air will be free of VOCs.

Do you need to replace any filter?

No, you don’t have to 🙂 The filter (electrodes) are reusable and easy to wash.

Do you need to turn off the system when you are away from home?

Leave the U400 on all the time! Let your place be filled with of clean and fresh air 🙂 The running cost of keeping the U400 on 24/7 is only $8 per month. This is a small amount in exchange for clean and fresher air!

Why we don’t use Hepa filter like others?

Hepa filter has two disadvantages:

    1. Hepa Filters have to be changed frequently for it to filter air more efficiently, which means more costs are involved. The average cost to replace a new set of Hepa filter ranges from $80 to $150, depending on the air purifier model. The suggested frequency to change Hepa filter is every 6 months.
    1. Hepa Filter has their limitations. It works ineffectively if the amount of air it has to filter is large and the airflow rate is low. Therefore the filtered air might not be clean and fresh all the time.

How do we clean the air without any filters?

P500 uses TPA technology to create clean and fresh air. TPA is filterless technology by silicon valley air experts. For more details please check here.

What is removable particles?

    • Mould spores – 100 – 2 microns
    • Pollen grains – 100 – 0.25 microns
    • House dust mite allergen – 25 – 0.1 microns
    • Bacteria – 25 – 0.25 microns
    • Pet dander – 10 – 0.1 microns
    • Toner dust – 10 – 0.1 microns
    • PM10 – 10 microns or less (PM = Particulate Matter)
    • Tobacco smoke – 4 – 0.01 microns
    • PM2.5 – 2.5 micronsor less
    • Viruses – 0.05 – 0.003 microns
    • Ultrafine particles – 0.1 – 0.001 microns
    • Haze – 10 – 0.01 microns

How U400 remove 0.02 microns particles?

U400 uses emitting electrodes to charge particles, the process is independent of particles size. Other filter-type technology, the filterable particles size is dependent on filters. (HEPA has a limit of 0.3 microns in particle size).

U400 uses collecting electrodes (act as a magnet) to pull all the charged particles as small as 0.02 microns.

How to maintain U400?

Simple remove the filter (electrodes), give it a good scrub with soap and rinse it under running tap water before putting it out to dry. Piece of cake isn’t it?

What is the warranty?

U400 has a one-year onsite warranty.  The TPA technology keeps the U400 operating for as longer as possible. Our customer support is here.

How to know if the surrounding air is clean?

Unlike other air system in the market, U400 provides air quality dashboard. You can read the indoor PSI directly from the front screen.

What is the maximum coverage of U400?

The maximum coverage is 60 square meters or 600 square feet.

What does the app do?

You can install our smart app which allows you to view the air quality dashboard in your phone and control the running mode anytime and anywhere on the go.

Is TPA similar to ionizer?

No, TPA is totally different from ionizer.

TPA uses electrodes to collect particles while ionizer doesn’t!
