Which one would you choose for better dehumidifying, rotation or molecular?

Dehumidifier, according to it’s functions and applications, can be divided into rotary dehumidifier and molecular sieve dehumidifier, So which one will you choose?  

Recently, a report from the local community，said that the dew-point temperature of molecular service dehumidifier is about -32℃,  which will be -20℃ after using for one year，and -10℃ half and one years later，so service life is just two years，while，rotary dehumidifier，in the advantage of dew-point temperature which is -40℃，and even -50℃ with enhanced configuration，his service life can reach 8 years or more

    Rotary dehumidifier take preference if it’s within your budget.

Otherwise , you may be troubled to replace dehumidifier frequently.
