?Is the home water purifier healthy and safe
Yes, absolutely, for the following reasons:

Thanks to God, our wise government provides homes with potable water. Factors that may affect water quality include poor home plumbing, unclean tanks, and variations in mineral content from one home to another
All our water purifiers contain at least six filters designed primarily to remove water contaminants. The added value of reverse osmosis (RO) purifiers lies in their ability to remove dissolved solids, including salts

?Made in the USA, Taiwan, or China
The country of manufacture does not affect the quality of the device. All Naqi purifiers are manufactured according to Naqi’s specifications and quality standards
All devices are covered by Naqi’s warranty against manufacturing defects for 2 years, with 5 years of free service, so there’s no need to worry

?What is the nationality of the technicians
All our technicians are specialists from various Arab countries

?Are the technicians qualified
We have a strict training policy with approximately 200 hours of training. Technicians then undergo rigorous testing to ensure they are fully qualified before being officially certified.

?Where are Naqi’s stores and headquarters
Naqi has branches in several Saudi cities, including Riyadh, Dammam, Najran, Tabuk, Al-Rimal, and Al-Ahsa
We are also present on online marketplaces like Noon and Amazon, making it easy to purchase from home

Naqi’s headquarters and customer service are located in northern Riyadh, specifically on Olaya Street. For a visit, you can search on Google Maps for “Naqi Water Purification,” where we are available to meet your needs and answer inquiries

?How often should filters be changed, and what are the prices
Regular maintenance is every 6 months, replacing stages 1, 2, and 3. After one year, stages 5 and 6 (and 7, if applicable) are added. After two years, stage 4 is replaced.

6-month maintenance: Stages 1, 2, 3 — 129 SAR (including installation and tax)

1-year maintenance: Stage 5 — 79 SAR

For 7-stage devices: stages 5 & 6 — 144 SAR

For 7-stage devices: stages 5, 6 & 7 — 187 SAR (including installation and tax)

?How much purified water does the device produce
The device produces 240–300 liters per day, equivalent to 12–18 large water bottles (jugs)

?How long does it take to fill the supplied tank
The speed depends on the cleanliness of the home water, but generally, the device can fill 15–20 liters in approximately 15–20 minutes

?What is the salt content after installation
The device purifies water to approximately 50–120 TDS, making it pure and safe for drinking

It is also possible to completely remove salts, as the body obtains necessary minerals from food
