Windsor Filter Bag for Flexamatic FM12, FM15 and Axcess Uprights (WI-7029)
The bag is not just a container. On a commercial upright it is the primary filter, and it is the part that determines both how much dust stays out of the air and how much suction the machine has left at the end of a shift. A bag run too long does two things at once: airflow drops as the pores load with fine dust, and the filtration that was protecting the motor starts to fail.
This is the correct replacement bag for the Windsor Flexamatic FM12 and FM15 and for Windsor Axcess uprights, cross-referenced to Windsor part numbers WI-7029 and 86284790.
Built for
- Windsor Flexamatic FM12 and FM15 upright vacuums.
- Windsor Axcess uprights.
- Occupied-building cleaning, where what the vacuum emits matters as much as what it picks up.
- Facility and janitorial teams stocking consumables for a fleet of Windsor uprights.
Change the bag earlier than you think
The common mistake is running a bag until it is visibly full. By then the machine has been underperforming for a while, because fine dust clogs the bag material long before the bag fills with visible debris. The practical rule for commercial routes is to change on a schedule tied to hours run, and to change immediately whenever suction noticeably drops or the motor note rises. A fresh bag is the cheapest item on the parts list and the one that most directly affects how well the machine cleans.
Why the right bag matters
Bags are not interchangeable between machine families, even when they look similar. A bag that does not seat correctly in the collar lets unfiltered air bypass the filter media entirely, which means dust straight through to the motor and back into the room. If a bag takes force to fit, it is the wrong bag. Match the part number to the machine rather than to the shape of the cardboard collar.

Frequently asked questions
Which machines does this bag fit?
Windsor Flexamatic FM12 and FM15, and Windsor Axcess uprights. If your machine is a different Windsor family such as the Sensor line, it takes a different bag. Send us your model number and we will confirm.
How often should I change the bag?
Change on a schedule rather than waiting for the bag to look full, because fine dust restricts airflow well before that. Change immediately if suction drops noticeably or the motor pitch rises during use.
Can I shake out and reuse a bag?
No. Emptying and reusing a filter bag does not restore the filter media, which is already loaded with fine dust, and handling a used bag releases that dust back into the air. Fit a new one.
What happens if I run the vacuum with a torn bag?
Dust bypasses the filter and goes to the motor and out into the room. A torn bag should be replaced right away, and the machine airway checked, since whatever tore the bag may still be inside.
