Generally, there are four kinds of filter elements for all types of baby bottle sterilizers:
1. Nylon
A filter device that is better than nothing, its material is ordinary nylon plastic. It is a bit similar to the cheapest shoe-shine sponge, with a loose structure, large and many pores, and basically no filtering and adsorption.
2. Activated carbon
Activated carbon is a kind of microcrystalline carbon material made of carbonaceous material with black appearance and developed internal pore structure. Activated carbon has adsorption properties, but it is mainly used to absorb odors. For example, benzene and formaldehyde in the air can be effectively filtered. However, the adsorption effect of fine dust is not very good, and there will be a certain risk of secondary pollution.
3. Non-woven fabric / pearl cotton / PP cotton
Relatively useful filtering device, the material is similar to a mask or cotton soft towel. Compared with Nylon filter, its filtration, shielding, heat insulation and oil absorption are all good. But the tightness is low, and it can only isolate large particles, and it can't do anything about finer mist dust and germs.
4. HEPA
HEPA (High efficiency particulate air Filter), the air purifiers and fresh air fans we know all use HEPA for air filtration. It can efficiently filter bacteria, dust particles, PM2.5 (fine particles with a diameter less than 2.5 microns), chemical smog and pollen through interception, gravity, airflow and van der Waals force. It can be said that the filtration performance is the best A kind of material, there will be no risk of secondary pollution.
HEPA is also subdivided into many grades of G1-G4, F5-F9, H10-H14 and U15-U17, but this already involves the scope of the air purifier HEPA standard. The job of the baby bottle sterilizer is to sterilize. It can be filtered with the most basic HEPA, and drying is enough.
Therefore, these four types of filter elements are better options for the feeding bottle sterilizer manufacturer.
Generally, there are three types of chassis materials for feeding bottle sterilizers:
1. Teflon
Teflon (polytetrafluoroethylene) is non-adhesive, has an extremely low coefficient of friction, and is a good self-lubricating material. So the amount of scale it produces will be very small. Even if scale occurs, it is very convenient to clean it with citric acid.
Some people will question the safety of Teflon, whether it will release toxins at high temperatures. Don't worry about this, the maximum temperature of the bottle steam sterilizer and dryer is about 100°C-120°C, and the melting point of Teflon is 260°C, so there will be no toxins produced by Teflon under high temperature heating.
2. Stainless steel
Because the cost of 304 stainless steel is lower than that of Teflon, most steam bottle sterilizers like to use it as the chassis material. Moreover, the 304 stainless steel is food-grade, and its safety is guaranteed. But because stainless steel is more prone to scale, and there will be a rust smell.
3. Tao Jing
Due to the addition of a layer of coating on the surface of the ceramic crystal, it is not easy to generate scale and is easy to clean. It can be said to be the material with the best anti-scale effect. But so far, Tao Jing has a relatively big problem, that is, the coating is prone to large pieces of peeling off and blackening. The main reason may be that the ceramic crystal technology of the chassis of the sterilizer is not yet mature, so there are no big-name baby bottle sterilizers on the market that use ceramic crystal to make the chassis.
