Question: what is the difference between dyson tp03 and tp04?
Answer: Filters. The Dyson Pure Cool air purifier (TP04) comes equipped with two filters. ... We have already come across this filter configuration while reviewing the TP03, but the length of material used in the HEPA filter has increased this time from 6.7m in the TP03 to 9m in the TP04, thus improving the efficiency.
