Question 1

What does a whole-house water filter actually treat?

Accepted Answer

The PureTap three-stage system is installed where water enters the property, so filtered water travels to your kitchen, showers, bathrooms, laundry and appliances rather than a single outlet.

Question 2

What are the three stages?

Accepted Answer

Stage 1 is sediment filtration with three-layer technology and up to 1-micron accuracy. Stage 2 combines KDF 55 and KDF 85 with natural coconut carbon for heavy-metal reduction and taste improvement. Stage 3 combines limescale-reduction media with natural coconut carbon.

Question 3

Will it reduce water pressure?

Accepted Answer

The system uses full-size 20" × 4.5" housings and is designed for an operating flow of 50–60 L/min, which suits normal household water demand.

Question 4

Do I need reverse osmosis as well?

Accepted Answer

Reverse osmosis is optional and focuses on drinking water at the kitchen sink. It adds stages 4, 5 and 6 — an RO membrane, T33 post carbon and a mineralisation and alkalisation cartridge.

Question 5

What does the RO membrane reduce?

Accepted Answer

It is designed to reduce PFAS, fluoride, total dissolved solids, radium and barium. Performance varies with incoming water conditions and filter condition.

Question 6

What is the mineralisation stage for?

Accepted Answer

The final cartridge is designed to reintroduce selected minerals and adjust water characteristics following reverse osmosis, using Maifan stone, mineral media, alkaline media and antibacterial media.

Question 7

Who installs the system?

Accepted Answer

PureTap systems are professionally installed. System configuration, mounting position and connection to the incoming supply are tailored to the property.

Question 8

Where is the whole-house cabinet installed?

Accepted Answer

Typically on an external wall near the incoming water supply. Cabinet dimensions are 74 × 59 × 21 cm, and the position is confirmed during your free water check.

Question 9

How often do filters need replacing?

Accepted Answer

Whole-house stages 1, 2 and 3 have a recommended replacement interval of 12 months, with maximum intervals of up to 18 months depending on conditions. For reverse osmosis, the membrane is 24 months and stages 5 and 6 are 12 months.

Question 10

Do you supply replacement filters?

Accepted Answer

Yes. Ongoing PureTap filter support means we supply replacements and can arrange servicing when stages are due.

Question 11

How accurate are the performance figures?

Accepted Answer

Reduction figures are based on laboratory tests using specific water formulations. Actual performance varies with incoming water conditions and filter condition, and results are not presented as guarantees.

Question 12

Does the whole-house system reduce fluoride?

Accepted Answer

Fluoride reduction is not part of the standard three-stage whole-house system. Fluoride reduction is associated with the reverse osmosis membrane on the drinking-water system.

Question 13

How do I get a price?

Accepted Answer

Enquire now. After reviewing your property and water concerns, you receive a clear recommendation and an installed quote.

Question 14

Is the water check really free?

Accepted Answer

Yes. No payment is required and there is no obligation to proceed after the assessment.
