Waterdrop reverse osmosis water filter system adopts advanced composite filter technology. The composite filter can intercept most harmful contaminants.
(1)TDS, chlorine, taste and odor, chloramine, scale, turbidity.
(2)Carcinogens: chromium (hexavalent), chromium (trivalent), cadmium and cadmium compounds, ferric oxide.
(3)Heavy metals: lead, mercury, barium, copper, radium 226/228, aluminum.
(4)Micro organic contaminants: cysts.
(5)Inorganic pollutants: arsenic and inorganic arsenic compounds, fluoride.
(6)Organic pollutants: asbestos, benzene, formaldehyde, trichloromethane, chlordane, PFOA & PFOS, etc.

The RO does not make the water unhealthy in any way. Instead, the purification process may protect the body from many contaminants present in the water.

Yes, but only up to 500 TDS/ppm of incoming source. Water that is harder than that can cause the filters or system to clog. In order to avoid this situation, you may need to install prefilter and a NOT salt based softener or scale inhibitor prior to the system.

Tank reverse osmosis system holds reverse osmosis water so you have plenty to use when you need it. A traditional tank reverse osmosis system makes water slowly. It takes one minute to produce two to three ounces of RO water. If you were to turn on your faucet for a glass of water at the actual membrane production rate, then you would have to wait at least 5 minutes for it to fill. Waterdrop tankless reverse osmosis system has overcome the issue of bacteria colonizing in the bladder tank. With no storage tank to fill, Waterdrop tankless reverse osmosis system does not run until RO water is needed.

No. Waterdrop RO systems are designed for DIY installation. You can install the system in 30 minutes. Simply refer to the instruction manual and instructional videos, or contact us by email, phone, or live chat.
This video explains how to install Waterdrop RO system.

All Waterdrop Pitcher and Dispenser filters are NSF 42 certified for the reduction of chlorine, taste and odor. It is also NSF 372 certified for lead-free material. Using 7-stage water filter technology, this water filter pitcher can effectively reduce arsenic, fluoride, lead, and other contaminants in water.

Step 1. Wash your hands, then remove filter from filter box.
Step 2. Please soak it in cold tap water for 10 minutes to remove bubbles before use to activate the filter and ensure the best filtration performance.
Step 3. Please hand wash the pitcher, dispenser, lid and reservoir with a mid detergent. Don’t put it in the dishwasher. Do not use abrasive cleaners rinse thoroughly with water.
Step 4. Install filter into reservoir. Press firmly to ensure a tight seal.
Step 5. Fill the reservoir with cold tap water. Discard the first two times filtered water.
Step 6. Press the button for 3 seconds until the blue light flashes to activate the indicator.Note: Repeat this step after each new filter replacement.

Our filters usually take 10-15 mins to filter the reservoir of water in your pitcher. One common cause of slow filtering is high levels of sediment in tap water, such as sand or rust that could clog a filter; hardness like limescale, or a grain of carbon which is blocking the holes. If your water contains high levels of sediment, consider installing a prefiltration system, such as these ones. Also, you can try removing the filter, shake it thoroughly to move the granular carbon around, then put it back in the reservoir.

First of all, please try resetting the filter by pressing down the button 6 times in a row and then hold it for 5 seconds.
If you've been using the pitcher for around a year, it can be that the indicator battery is worn out and needs to be replaced.
If after these options, the light still doesn't turn on, please contact us to help you replace it.

One possible cause for an apparent leak may be overfilling. Water may overflow into or over the handle when you pour resulting in what appears to be a reservoir leak.
If the reason for the leakage appears to be due to the faulty product or damage, please contact our Support, so that we can address the issue accordingly. We offer a 30-days guarantee in case the product gets damaged.

If your faucet system hasn’t been used for several days, wet and reactivate the system’s filter by running water through the filter for 30 seconds.

It is an conveniently visible reminder of filter replacement time. BLUE light on means that the filter is working well. When it turns RED and flashes, you need to get ready to replace the filter. If the light stays on RED for 5 seconds, it’s time to get the filter replaced soon.

The lifespan of a water filtration system for home can vary significantly depending on several factors:
Type of Water Filter: Different types of filters have different lifespans. For instance, sediment filters may need to be replaced every few months, while more advanced multi-stage filters could last longer.
Quality and Capacity of the Filter: Higher quality filters with larger capacities can last longer than basic models.
Water Quality: If your water has a high level of contaminants or sediment, filters will clog and need replacing more frequently.
Water Usage: The more water you use, the faster the filter will reach its filtering capacity and require replacement.

On average, here are some general guidelines for the lifespan of common types of whole house water filters:
Sediment Pre-Filters: Every 2-6 months.
Carbon Filters: Every 6-12 months.
Reverse Osmosis Membranes: Every 1-2 years.
Water Softeners and Conditioners: These can last several years but may require maintenance or resin replacement.

HSA/FSA accounts were created so individuals could use pre-tax money to pay for expenses used to treat, mitigate, or prevent a diagnosed medical condition. Because HSA/FSAs use pre-tax money, you’re getting more purchasing power for your dollars. Rather than pay taxes on income and then spend it on health items, qualified customers can use pre-tax funds to invest in their health.

An individual can contribute up to $4,150 pretax to their HSA per year, or $8,300 for a family (plus an additional $1,000 if you are at least 55 years old. Individuals can contribute up to $3,200 pretax to their FSA per year (with an additional $500 in employer contributions allowed).

Health savings accounts (HSA) and flexible spending accounts (FSA) are programs that allow you to set aside pre-tax dollars for eligible healthcare expenses. If you’re unsure whether or not you have an HSA or FSA account, please check with your employer or insurance company.

Yes, simply select Truemed as your payment option at checkout and use your FSA or HSA card as you would any other credit card.

Yes. If you prefer to use your regular credit card, Truemed will send you instructions on how to submit for reimbursement from your HSA//FSA administrator.

The items in your Truemed Letter of Medical Necessity (“LMN”) are now qualified medical expenses in the same way a visit to the doctor’s office or pharmaceutical product is.

There are thousands of studies showing food and exercise is often the best medicine to prevent and reverse disease. Exercise qualifies as a qualified medical expense with an LMN. Food, supplements, and other wellness purchases qualify as medical expenses if they treat or prevent an illness, and a doctor substantiates the need. Your Truemed LMN satisfies all IRS requirements to make your wellness spend fully reimbursable.

There is no cost to you, as long as you are shopping with a Truemed partner merchant.

You can use your HSA/FSA dollars all year long. However, FSA dollars expire at the end of the year and unused money may not rollover into the next year. Make sure to spend the rest of your FSA dollars before December 31st — use it, so you don’t lose it!

Generally it takes 24-48 hours. In some cases, Truemed’s provider team will require additional time to issue a letter of medical necessity based on the needs associated with an individual qualification survey. If you aren’t seeing your letter in your inbox, check spam, then reach out to us at support@truemed.com for help.

Unfortunately, Truemed’s services are for individuals who have HSA or FSA accounts (or plan to fund one during open enrollment). We encourage you to ask your employer about information on your HSA or FSA!

Unfortunately, Truemed is currently only available in the United States.
