How safe is your litter?

Artificial odor control by litter
Most modern litters are artificially enhanced for odor control. These come at a risk, as cats are in direct contact with the litter and may ingest hazardous particles while grooming their fur and paws.

Natural odor absorption by Magic Blue
Magic Blue efficiently reduces ammonia and cat pan odors from a safe location outside of the litter. The filter pads contain a special resin that absorbs and retains odors like a big sponge. This is an entirely natural process that doesn’t involve any kind of chemical or toxin.

Chemical sprays try to camouflage bad odors by adding even more unhealthy gasses to the air.
Magic Blue is unscented, non-toxic and improves the air quality for you and your cat.

Reduce cat pan odors

reduces odours

Magic Blue will reduce up to 40% of cat pan odors, depending on your cat’s diet.

Follow your cat's instinct

cat's instinct

In nature, cats use feces and urine to mark their territory. Indoors, these odors can build up quickly.

A cat’s sense of smell is about 15 times stronger than our own. So when ammonia and foul odors build up inside of the litter box, we certainly aren’t doing our cat any favors.

Magic Blue minimizes odors without erasing your cat’s scent mark from the litter box.

Excessive cleaning and scented sprays can distress and confuse your cat to the extent it stops using the litter box, especially when other cats are close by.

No hooded cat pan needed
to enjoy the effect!

Simply place Magic Blue in your trashcan and experience the magic every time you open the can.
The smell will be reduced by an average of 50% or more, depending on the contents.

1 Magic Blue = 25 carbon filters!

To be absolutely sure that Magic Blue really works, we sent the product to an independent laboratory for meticulous testing. First, either Magic Blue or carbon filter pads were placed in the top filter gap of a hooded litter box. Next, ammonia was added. The air that exited the litter box through the filter gap, was analyzed for ammonia content, which revealed the rate of absorption.

What is ammonia?
Ammonia (NH3) is one of the most commonly produced industrial chemicals. It is used in industry and commerce, and also exists naturally in humans and in the environment. Ammonia is essential for many biological processes and serves as a precursor for amino acid and nucleotide synthesis. In the environment, ammonia is part of the nitrogen cycle and is produced in soil from bacterial processes. Ammonia is also produced naturally from decomposition of organic matter, including plants, animals and animal wastes.
Some chemical/physical properties of ammonia are:

  • At room temperature, ammonia is a colorless, highly irritating gas with a pungent, suffocating odor.
  • Ammonia has alkaline properties and is corrosive. 

What is ammonia’s mechanism of action?
Ammonia interacts immediately upon contact with available moisture in the skin, eyes, oral cavity, respiratory tract, and particularly mucous surfaces to form the very caustic ammonium hydroxide. Ammonium hydroxide causes the necrosis of tissues through disruption of cell membrane lipids (saponification) leading to cellular destruction. As cell proteins break down, water is extracted, resulting in an inflammatory response that causes further damage.

How is ammonia exposure treated?
There is no antidote for ammonia poisoning, but ammonia's effects can be treated, and most people recover. Immediate decontamination of skin and eyes with copious amounts of water is very important. Treatment consists of supportive measures and can include administration of humidified oxygen, bronchodilators and airway management. Ingested ammonia is diluted with milk or water. 

What are the immediate health effects of ammonia exposure? 
Inhalation: Ammonia is irritating and corrosive. Exposure to high concentrations of ammonia in air causes immediate burning of the nose, throat and respiratory tract. This can cause bronchiolar and alveolar edema, and airway destruction resulting in respiratory distress or failure. Inhalation of lower concentrations can cause coughing, and nose and throat irritation. Ammonia's odor provides adequate early warning of its presence, but ammonia also causes olfactory fatigue or adaptation, reducing awareness of one's prolonged exposure at low concentrations.

Children exposed to the same concentrations of ammonia vapor as adults may receive a larger dose because they have greater lung surface area-to-body weight ratios and increased minute volumes-to-weight ratios. In addition, they may be exposed to higher concentrations than adults in the same location because of their shorter height and the higher concentrations of ammonia vapor initially found near the ground.

Skin or eye contact: Exposure to low concentrations of ammonia in air or solution may produce rapid skin or eye irritation. Higher concentrations of ammonia may cause severe injury and burns. Contact with concentrated ammonia solutions such as industrial cleaners may cause corrosive injury including skin burns, permanent eye damage or blindness. The full extent of eye injury may not be apparent for up to a week after the exposure. Contact with liquefied ammonia can also cause frostbite injury.

Ingestion: Exposure to high concentrations of ammonia from swallowing ammonia solution results in corrosive damage to the mouth, throat and stomach. Ingestion of ammonia does not normally result in systemic poisoning.

Tips & Tricks

Does Magic Blue really work?
That’s a good question! In truth, we were equally hesitant when we started testing the first lab samples. As it’s not possible to remove every single type of odor, our R&D department geared the pads towards ammonia reduction, which is the most pungent and harmful gas in cat urine. We performed a few simple tests of our own, with exciting results: significant odor reduction and an amazing absorptive capacity for ammonia!magic blue testing

I installed Magic Blue, but the litter box still smells?
Magic Blue is most effective in hooded litter boxes, combined with sensible litter box hygiene. In short, you will get better results if you scoop and clean the litter box on a regular basis. And when you find the foul odors still persist, you may want to try changing your cat’s diet, because what goes in will naturally affect what comes out. You could even try replacing the litter box altogether, as the plastic tends to absorb foul odors over time.

I have always used deodorizers and my cat never once complained. Why change now?
While chemical deodorizers are often part of our own toilet hygiene, we can’t push our habits onto our pet cats. Cats often suffer the consequences of frequent, direct exposure to these chemicals, which are extremely toxic and hazardous to their health. It sticks to their fur and paws and even becomes ingested during daily grooming. Symptoms range from facial tics to cancerous growths and can be fatal. Luckily the solution is simple: don’t use chemicals. Your cat’s litter box will be a safer and healthier environment for it.

How does Magic Blue work?
It’s simple: by developing a unique procedure, we created Magic Blue - a type of sponge with microscopic pores that are perfectly sized for ammonia absorption. This material is extremely effective in absorbing and retaining ammonia and other foul litter box odors, with results from 30% to 80% reduction depending on the odor makeup.

Sounds good, but do you have proof?
To be absolutely sure that Magic Blue really works, we sent the product to an independent laboratory for meticulous testing, the results of which are mentioned above. But you don't have to take our word for it! If you want to test Magic Blue for yourself, you can do so easily with this DIY test. 

I noticed the smell slowly returning. Why is that?
Not to worry, this simply means the Magic Blue filter pads need replacing. The pads will keep on absorbing ammonia and foul odors until they’re fully saturated and have reached their limit. In general, two pads are effective for 1 month, but may last less long if your cat is on a specific diet or makes excessive use of the litter box. Simply insert two new Magic Blue pads into the cartridge and you’re all set.

Will Magic Blue remove all of the odors?

Magic Blue is a soft odor reducing filter that improves the air quality without adding forced chemical scents. As such, it may not take away all of the smell, especially not at once. Instead, Magic Blue absorbs and neutralizes hazardous ammonia gases, cancelling out the most pungent of litter box odors.

How can I recycle the used pads?
Used Magic Blue filter pads are much easier to discard than plastic filters or spray cans.  Simply discard the pads in the bin. The plastic cartridge can be cleaned and reused over and over again to minimize waste.
