The All-fit model uses Xpure inside G2 filter material (CNS15980 Class B), while the basic model uses Xpue inside G1 filter material (CNS15980 Class D). Therefore, the All-fit model is better than the basic model in terms of filtration effect! Of course, both can also withstand 200 washes.

There are two features that are unique to the All-fit model and different from other styles:

1. Extremely pure black design inside and out, low-key and versatile
2. There are three sizes: large, medium and small, suitable for any face shape (other styles only have a single size M)

Both the All-fit model and the Beauty model are available, but the basic model does not have the following features:

1. Using Xpue nano protective layer-G2 filter material
2. The pattern is fine-tuned, and the lower edge curve is pulled upward, giving a more visual effect to small faces.
3. The ear straps are upgraded to use cylindrical pressure-reducing structure ear straps, which are more comfortable, durable and less likely to age.

By the way, the features that are unique to the Beauty model and not found in other models are as follows:

1. Using collagen peptide cherry blossom powder lining, it has skin-friendly and moisturizing effects, and is antibacterial, deodorant and anti-UV.
2. Table cloth using special materials: satin black & woolen gray
3. Use plush hard stitching labels instead of electric embroidery logos to enhance the low-key luxury texture.

Please scroll up. The copy explains how to determine the suitable size by measuring the "distance from chin to ear base". You can also refer to the Model's fitting report in the copy to assist in your judgment. If you still can't decide, you can refer to the following suggestions:

• Boys or girls of medium build (those with small faces will not be particularly described as those with small faces) are right to choose M.
  
• Boys who are tall or have thicker faces usually buy one size larger hat, so choose L
  
• Girls who are petite or who are often said to have small faces will feel a little loose when wearing ordinary medical masks, so choose S
  
• If you have worn our other styles of masks, since other styles are only M, if you think it is too small, you can choose L, and if you think it is too big, choose S!

The ear straps of the All-fit model are made of elastic fabric woven in a tubular shape. They do not contain rubber threads, so they are less likely to deteriorate. However, the elasticity will gradually become worse. After all, it is physically too difficult for elastomers to maintain their elasticity permanently. Too demanding. Therefore, the ear straps of the All-fit model are also removable and can be replaced by yourself. You can get new ear straps for an additional 15 yuan when shopping on the Net Convection official website. As for the replacement method, please refer to the instructional video on disassembling and assembling earbands and loops .

Please use wire (hairpins or paper clips, etc.) to pass through the hole of the collar first, then wrap the wire around the two ear straps, and then pull the wire and the two ear straps out of the hole of the collar. Or you can refer to the instructional videos or instructional pages we shot. .

The recommended number of cleanings is 200 times. The average person washes it about three days or once a week, so it can be used for about two years without any problem. The recommended cleaning method is "gentle hand washing". After all, the cleaning intensity of the washing machine in everyone's home is different. In addition, you can add general neutral detergent (cold detergent, hand soap, shower gel, etc.) to assist cleaning, or you can wring it out and dry it, but do not dry or iron it!
If you still want to wash it in a washing machine, be sure to put it in a laundry bag for protection, and set the cleaning and dehydration modes to soft wash, which will be safer. In addition, please be careful not to twist the wire on the upper edge of the mask too much when wringing it out to avoid the wire from breaking due to undue stress.
