Declare war on viruses and bacteria!

January 12 2021, Patric Leibig

During the colder seasons, we spend more and more time in enclosed spaces, therefore increasing our risk of contracting viruses.
It only takes a short amount of time for us to lose our ability to assess air quality as we adapt to smells. This increases the importance of counteracting this.

Significantly reduce the risk of infection due to SARS-CoV-2 / Covid19 (Coronaviruses) and other viruses by using ambient air filters with Hepa H13 filter systems and CO2 monitors.

Air filters reduce aerosols in the ambient air.

SARS-CoV-2 / Covid19 and other lower respiratory illnesses are transmitted via aerosols/water droplets, amongst other things. Air purifiers with class H13 HEPA filters can filter these minute particles out of the ambient air and therefore significantly reduce the risk of infection. A combination of regular ventilation and air purifiers with class H13 “High Efficiency Particulate Air Filters” HEPA filters is the best way to reduce the risk of infection in enclosed spaces. H13 HEPA filters remove minute aerosols (<5µm) from the air and improve air quality. CO2 monitors can also be used to support ventilation.

According to estimates, the risk of a person in a room becoming infected with SARS-CoV-2 / Covid19 (coronaviruses) due to the presence of a superspreader is reduced sixfold by using air filters with H13 HEPA filter technology.

Monitor and improve the air quality in your office, your flat, the classroom, etc, using the following measures:

  • Proper and regular ventilation / cross ventilation
  • CO2 monitors which support your ventilation
  • Air purifiers / air filters with H13 or H14 “High Efficiency Particulate Air Filter” HEPA filters

Calculating the filter output for your room:

The ambient air filter should be able to filter the entire volume of air in the room at least 2x per hour in order to considerably reduce the concentration of aerosols and particulates. It is easy to work out the filter output you require:

To calculate the volume of your room, and therefore the volume of air, multiple the room’s length x breadth x height. Multiply this result by 2 and you have calculated the filter output in m³/h for your room.

Example:

Length: 5m, width: 4m, height: 2.5m

5m x 4m x 2.5m = 50m³

50m³ x 2 (per h) = 100m³/h

For classrooms / schools or other spaces where groups of people gather, we recommend calculating the air purifier’s output at 5 to 6 times the volume of the room.

Example:

For a room with a volume of 50m³, the air purifier used should have a minimum output of 300m³/h.

New: fabric masks with attractive astronomy themes

July 13 2020, Marcus Schenk

Whether you are going to the supermarket, the book shop or the public observatory; in all these locations you need to wear a mask. So why not wear one that you really like? Luckily, there are now new astronomy-themed masks. Beautiful images with the Pleiades and the solar corona during an eclipse. As a hobby astronomer and fan of outer space, make a statement with one of these masks.

A great addition to the Masketo fabric mask range, which were previously only available in black or white, in different sizes – including for children – or with the Corona Borealis design.

The solar corona: the Sun is one of the reasons why there is life on Earth. It is only a medium-sized star on the edge of the galaxy, but it is for us – along with our Earth – vitally important. This mask shows a total eclipse of the Sun, which occurs when the Moon moves in between the Earth and the Sun. By an absurd coincidence, the Moon and the Sun appear to be the same size in the sky, which allows us to marvel at the solar corona depicted on the mask during a total eclipse.

The Pleiades: the Pleiades were recognised in the sky even in the very early days, as found in a 17,000-year-old rock-drawing in a cave, or in an image on the ancient Nebra sky disk. Some people mistake it for the Little Dipper, but it is the best-known open star cluster in the starry sky. Just 400 light years away, large blue stars and only 100 million years old.

Summer theme: If you simply want to share a little summer with your mask, this one is ideal, with palm trees and fresh turquoise colour accents.

All Masketo masks are non-medical masks that can help reduce the spread of airborne droplets in the Corona crisis.

The benefits:

  • Themed mask
  • With elastic loops
  • 2-ply with wire for nose clip
  • Inner surface 100% cotton + outer surface 100% polyester
  • Washable at up to 60°C
  • Made in Europe

Note: these masks serve to reduce the risk of transmission in the environment through airborne infection. This is not a medical product within the definition of the MPG and not personal protective equipment (PPE).

Totally stylish, whether in the observatory or at the astronomy club: be sure to secure your fabric star mask today.

Now available: face masks

May 18 2020, Marcus Schenk

The corona virus is regarded as a cause of the Covid-19 (SARS-Cov-2) disease. The recently-implemented mandatory wearing of face masks helps us to contain the virus. Therefore, we are offering you cotton or polyester non-medical face masks, and special respirators with KN95 filtering effect.

Cotton face masks

Masketo’s washable fabric masks are black and are made of 100% cotton. This means: you can easily wash them in the washing machine at 60°C and reuse them. The nose clip can be adjusted as necessary, so you can be sure that the mask fits you perfectly. The big advantage over disposable paper masks: they save money, eliminate waste and most people find that breathing through a fabric mask is significantly more comfortable.

The masks from MYONE are also made of 100% cotton, are available in white, and are anatomically designed in sizes M and L. The advantage: they are just as comfortable as the Masketo black masks, however thanks to the design, a nose clip is not necessary. Therefore, you can also sterilize the mask in the microwave.

Note: These masks serve to reduce the risk of transmission in the environment through airborne infection. This is not a medical product within the definition of the MPG, and is not personal protective equipment (PPE).

Respirators with KN95 filtering effect

The respirators with the KN95 filtering effect  protect both you and your environment at the same time. According to Wikipedia, they are functionally equivalent to the FFP2 respirators, which are mostly reserved for medical staff. It’s just good to know you’re protected when you are out and about in public. Especially if you have contact with a lot of other people. This makes the KN95 masks great: because 95% of the particles greater than 0.3 μm are filtered.

Masks with astronomical designs

As a hobby astronomer or space fan you absolutely need something like this: face masks with astronomical designs. 

Although you could be mistaken: the name of the  “Corona Borealis” face masks has really nothing to do with the virus. It is the Latin name of the Northern Crown. The mask features the design of this beautiful constellation with its main star Alpha Coronae Borealis.

Good to know: Soon we will also be offering face masks with other attractive astronomical images.

Every purchase helps to save lives

Many countries have been badly hit by Covid-19, ventilation equipment and medical care is in short supply. How can we help? For every order we will forward EUR 1 to “Doctors Without Borders”. In the Corona crisis, the humanitarian organization fights against death and for life in more than 50 countries. Be a role model and join in: by purchasing a mask you are helping exactly the people who are desperate for your help.
