MiracleBag – Crystal Clear Pool Water Without Sand Filters

Por que escolher a MiracleBag?

MiracleBag is the original, custom-manufactured product
with a unique design you won’t find anywhere else. It is not just a simple filter bag,
but an innovative solution that allows your home pool, hot tub, or garden pond to
remain crystal clear without the need for complex or expensive filtration systems.
The industrial-grade filter material, with a fineness of 1 micron or 0.5 microns, is
capable of removing even the smallest suspended particles responsible for
opaqueness or cloudiness.

The MiracleBag filters out green algae, algae dust, and even iron or manganese
precipitated from well water, which often discolors the water. By using it, your water
will not only be visibly cleaner but will also provide a more chemical-free swimming
experience. The amount of chlorine and other chemicals can be significantly reduced,
resulting in fragrant, skin-friendly, and pleasant water. MiracleBag offers a
long-term solution for those seeking simple, effective, and safe pool maintenance.
Our custom-made material and proprietary technology ensure that no one else offers
a comparable solution—you are getting the authentic original.

Como funciona o MiracleBag?

The operation of the MiracleBag is simple yet highly efficient. All you need is a
submersible pump placed in the center of the pool floor to initiate water circulation.
Connect the filter bag to the pump’s outlet using a flexible hose (fitting a maximum
32–36 mm connector). The outflowing water creates a continuous circulation. By
securing the bag at the edge of the pool, as far from the pump as possible, debris is
naturally guided toward the pump, ensuring the water flows through the entire pool
and is constantly purified.

The results are exceptionally fast. After just a few hours of operation, the water
becomes crystal clear, eliminating the need for further vacuuming or lengthy
filtration processes. MiracleBag is available in various packages, including sets
optimized for larger pools and hot tubs. The industrial-quality filter material far
exceeds the efficiency of traditional paper or sand filters. You will immediately
notice the spectacular clarity and the reduced need for chemicals.

Cleaning and Maintenance

Maintaining your MiracleBag is incredibly easy and cost-effective. The bag should be
cleaned when the fibers become saturated with debris. Simply open the zipper and
wash the inside with a strong stream of water to remove accumulated dirt. For
stubborn deposits, a pressure washer may be used—but always with caution to
avoid damaging the filter material. The durability of the MiracleBag is outstanding;
with proper care, it can last 3 to 5 years.

It requires no expensive investment and works perfectly even with a basic
submersible pump. The original product guarantees reliability and peak
performance, backed by over a thousand positive customer reviews.

Technical Specifications and Accessories

The filter bag measures 100 × 15 cm, has a filtration surface of 0.3 m², and provides
efficient cleaning with 1-micron filtration fineness.

The product is available in several versions to meet different needs:

● 1-Unit Version: Universal design, recommended for pools between 0–20 m³.
Compatible with both submersible and external pumps.
● 2-Unit Pack: Ideal for larger pools between 10–30 m³.
● 3-Unit Pack: Recommended for pools between 15–40 m³.

Jacuzzi Set:

Specially optimized for hot tubs, spas, and small pools using a
submersible pump. Using the 1-micron system protects the internal circulation
system of your hot tub, preventing costly breakdowns. The submersible pump
delivers debris into the bag more efficiently while also suctioning sediment from the
floor.

Note: The Jacuzzi set includes a short flexible hose not suitable for larger pools, which
require longer hoses.

A Message from the Inventor: János Strausz

“Hi! I’m János Strausz, the inventor, founder, and owner of MiracleBag (known as
Csodazsák in Hungary). I have been developing innovative micro-filtration
technology for over 12 years. My goal is to replace complex and expensive sand
filters with a simple yet highly effective solution. I am not just a businessman; I am
here to help. I support our users with instructional videos and often personally
consult with customers to provide technical advice.”

MiracleBag – Sustainable and Efficient Pool Cleaning

MiracleBag is a modern, environmentally conscious solution. Its use eliminates one
of the biggest drawbacks of sand filters: significant water loss during backwashing.
You no longer need to flush out hundreds of liters of chemically treated water,
saving you money and protecting the environment.

The 0.5–1 micron filtration physically removes suspended solids and algae spores.
Consequently, fewer chemicals are needed, and the use of flocculants (coagulants)
becomes unnecessary. With fewer organic contaminants, chlorine works more
effectively, allowing for clear, transparent water even at lower chemical levels.

The system is economical: cleaning the bag requires only a few liters of water.

Thanks to the durable industrial material, the MiracleBag lasts for several seasons,
eliminating the need for disposable filters. It is a practical, cost-effective, and
sustainable alternative that increases cleaning efficiency while reducing water and
chemical consumption.
