Worst filtration system! |
|
Pros: |
Cons: |
|
- Build-up in canister of allergens,mold, bacteria, dust mites, fungi and other harmful pollutants, and foul odors
- Not very hygienic, very messy and dirty to clean
- Permanent filter - costly to
replace
- "Self-cleaning" feature is not effective; this could be misleading
- Clogs easier - can loose up to 60% suction over
time
- Motor works harder
over time causing higher electricity cost
- Must be vented outside
