How is it different from other whole house water filters?

In order to give you the benefits of clean and soft water, most whole house filters need two separate units (a filter and a softener), which add to your cost. The HardlessNG Lotus was engineered to solve both issues all in one compact unit. But even more important than cost, is the quality of the water that you get when using a HardlessNG filter. Most filters are carbon filters, which remove almost all of the chlorine in the water. Once all of the chlorine has been removed, your water is vulnerable to dangerous microorganisms. This means that as the water is going through your pipes, it may still collect whatever germs are in them. Because the HardlessNG Lotus is able to filter out the combined chlorine and leave in the more effective free chlorine, as the water travels through your pipes it is still able to kill any bacteria or germs that may have settled in the pipes, no matter what faucet they lead to. This ensures you that your water will always be germ free. But, not only is the water germ free, it is healthy. When removing the hardness from the water, the HardlessNG Lotus leaves in essential minerals that other salt based water softeners take out.

How does it work?

Inside the HardlessNG Lotus there are two main components: the stainless steel filter and a cartridge for reducing hardness. The cartridge sits inside the stainless steel filter. As water enters the unit it sprays through the cartridge. During this spray, the water passes over the crystals that modify the crystalline structure of the minerals that cause the problems of hard water. The water then sprays through the stainless steel filter. The filter’s advanced patented design, removes the combined chlorine leaving you with the more effective free chlorine. Combined chlorine does not disinfect very well, and can be very dangerous for people with compromised immune systems. By leaving in the free chlorine, it ensures you that your water is always germ free.
* It is important to note that the HardlessNG Lotus is meant for municipal water only. It is not meant for water that is considered to be microbiologically unsafe.

How is this different from reverse osmosis?

Reverse osmosis units are usually located in the cabinet under the kitchen sink, which means that that is the only place that will have purified water. They use pressure to push the water through a membrane and in the process filter out contaminants and minerals from the water. It takes anywhere from 1-5 gallons of water to achieve this result, which means for every gallon you get of drinking water, you have wasted on the average 3 gallons of water. This method can be costly and is not environmentally friendly. With a whole house water filter such as the HardlessNG Lotus you get clean healthy water at every tap, without wasting any water. Plus, the water from the HardlessNG Lotus will still contain all the essential minerals that were intended from nature.

How does it treat the water?

Traditional water softeners replace the minerals (calcium and magnesium) in the water with sodium ions. This adds salt to the water, which is bad for you, bad for the pipes, and bad for the environment. Many water softeners also may need an additional unit to filter the water from the water softener; this of course will cost you extra.
The HardlessNG Lotus leaves in the calcium and magnesium because they are healthy for you to drink but modifies their crystalline structure so that they do not cause the problems of hard water.

What is bad about hard water?

There is nothing bad about drinking hard water. Hard water is water that contains minerals, usually calcium and magnesium, which are good for you.
As for your home, that’s another story. Hard water causes lime scale to build up in your pipes and water appliances, which reduces their efficiency. It leaves a film on bathtubs and shower tiles, and that same film is left on your hair causing it to be dull and on your skin causing it to be dry. It can also leave water spots on your dishes and clothes washed in hard water tend to feel hard and look dingy.

What kind of water can the filter be used with?

The HardlessNG Lotus should be used with municipal water only. It is not meant for water that is microbiologically unsafe to drink. It can only be used with well water if the water has been through a chlorination process.

So why buy a HardlessNG Lotus if the municipal water is already okay to drink?

The reason the water is okay to drink is because chlorine has been added to it. The good part about chlorine is that it kills microorganisms, which can cause illness. The bad part about chlorine is it causes the water to taste bad, smell bad, and can dry out your skin and hair, not to mention the chlorine vapors that are released into the air when you shower or use your dishwasher. Carbon filters remove almost all of the chlorine, leaving the water susceptible to dangerous microorganisms. The patented design of the stainless steel filter in the HardlessNG Lotus can leave in just the right amount of chlorine, so that your water is always germ free.

Is there any loss in water pressure?

No. The patented design of the stainless steel filter uses the filtration and separation technology so that when water passes through it, it separates precipitates encapsulating them in a “precipitate trap” at the bottom of the filter cup using hydrodynamic forces. This maintains the water pressure despite the fine filtering. This method is different from others because there is no bacterial growth in the filter, and fresh water never flows through an existing contaminant bed. In addition, it does not reduce the values of the remaining chlorine.

How long does the unit last?

The HardlessNG Lotus has a 4 year limited warranty that covers any parts that may be defective in workmanship and/or material.

What is the maintenance and do any parts need to be changed?

The stainless steel filter is good for the life of the filter and never needs to be replaced. The cartridge needs to be replaced every 6 months and can be bought online or by calling 1888-855-1802.
To keep the filter working like new, once a month you need to turn the valve on the bottom of the unit and let the water run for one minute. This will create a cyclone effect inside the unit that cleans out the stainless steel filter and gets rid of any deposits.

What will happen if I forget to wash out the filter or to change the cartridge?

You will not damage the filter, but you will notice a change in the taste of your water. This will remind you that you probably need to wash it out. If you forget to change the cartridge after 6 months, you may see some white stuff building up on your counters, toilets, or spots on your dishes. Once you wash out the filter or change the cartridge, you will have the same results as when you first had it installed.

Is the HardlessNG Lotus environmentally friendly?


There is no wasted water and no salt.

Reverse osmosis systems use 2-5 gallons of water for every clean gallon of drinking water. Every gallon of water that passes through the HardlessNG Lotus is drinkable healthy water. Also, most other filtration systems need to do a backwash every 10-14 days. This backwash can take anywhere from 25-40 gallons of water that gets wasted. The HardlessNG Lotus needs to be flushed out once a month, which usually takes about 10 gallons of water that can be used to water the plants in your garden.

Is the HardlessNG Lotus for everyone?

If you are looking for the simplest and most affordable answer to your water problems whether they are taste, smell, dry hair and skin, or even lime scale, then HardlessNG Lotus is the right filter for you. With Hardless you don’t need to buy another unit to add on to solve the problem caused by a different unit. You can have clean healthy water, and solve the lime scale and water spot problem all with one compact affordable unit.

What certifications does the HardlessNG Lotus have?

The crystals that are used for reducing hardness are certified by NSF 42 and NSF 60.

Technical Information

Stainless Steel Filter
The HardlessNG Lotus has a multi-layer, stainless steel filter with a protective coating. This filter achieves optimum results and removes dirt, sand, water borne parasites, scale and bonded chlorine.

The Scale Solution
In the HardlessNG Lotus, scale is removed by the cartridge containing slow phos crystals which are a polyphosphate with very low solubility.

Hardless Takes out the Chlorine to Improve Taste and Smell
Chlorine is added to drinking water to prevent the growth of bacteria and viruses. When chlorine meets organic compounds, the result is organochlorides, which are known to be carcinogenic.
About 80% of the chlorine used to disinfect becomes harmful, bonded chlorine products.
The remaining chlorine in the water ensures that there is no microbial development.

HardlessNG Lotus is not a “hard water Softener” but can reduce the problems caused by hard water
The HardlessNG Lotus prevents scale build up by modifying the crystalline structure of the calcium and magnesium in the water, so that your pipes and water appliances do not get hard water damage. No Salt is used in the HardlessNG Lotus.

Maximum Scale Treatment and Maximum Water Quality
The slow phos crystals in the cartridge are designed to deal with scale to the healthiest possible level, but without any compromise on water quality. Water exiting the cartridge complies with the very stringent Australian / New Zealand Standard AZ/NZS 4020:2005 and always meets drinking quality standards.

Scale Treatment for the Maximum Possible Time
The cartridge is designed specifically to ensure that the water enters the process through a spraying system directing the flow onto the slow phos crystals to maximize contact between the water water and the crystals.

TAP – The Smart Way to Remove Deposits
The TAP mechanism – Operating the lower tap initiates an internal process including cyclonic water circulation and the introduction of a bubble of air to take up volume. The cyclone effect increases the speed of water flow, which sucks the deposits out of the filter and spins them away.

The Value of Size and Symmetry
Because of the compact size of our filter, it is perfect for homes and condo units where space is at a minimum. The system can easily be installed by any licensed plumber.

Easy, Fast Installation
Unique connectors with internal fixtures for the simple, fast installation of HardlessNG Lotus 1” pipes.

Easy Opening Filter Housing
Opening the filter housing to replace the filter can be a nightmare in almost every known filtering system.
The HardlessNG Lotus is different.


The drain tap is opened once a month to initiate cyclone cleaning of the deposits and scale trapped by the filter.

Replacement of the cartridge once or twice a year (depending on the amount of scale removed).
