Lindhaus Type A4 Vacuum Bags (8 Pack) + 2 Exhaust Filters

These are the genuine Lindhaus A4 bags, part 031100019 — the bag that goes in most of Lindhaus’s domestic and light commercial uprights. One box holds eight bags and two exhaust filters, which Lindhaus reckons is about a year in an average home. Which machines take this bag Activa 30 Platinum Activa 30 Pro Commercial Activa 38 and Activa 38 Pro Diamante 300E Diamante 380E Dynamic 380 and the Dynamic eco FORCE range The box says Activa — that is normal Lindhaus prints one box for this bag and the picture on it is an Activa. It is still the correct bag for the Diamante and the Dynamic, which is what Lindhaus’s own parts listings show. Nothing has gone wrong if the carton only names the Activa. Do not confuse this with the PH4 Lindhaus makes two paper bags of almost exactly the same size for its uprights, and they do not interchange. This is the A4, sold in eights. The other one is the PH4/L4, sold in tens, and it fits the RX eco FORCE, HEALTHCARE Pro and CH Pro. The quickest way to tell which you have is the count in the box you last bought — eight means A4, ten means PH4. If you are not sure, call 888-565-6163 with your model number and we will tell you in a minute. Specifications Lindhaus part number 031100019 Type A4 In the box 8 paper bags, 2 electrostatic exhaust filters Capacity 4 liters (about 4.2 quarts) Material 2-ply high filtration paper Filtration Certified 98.28% net efficiency at 0.3 micron Genuine Yes — Lindhaus original, not an aftermarket copy Why the bag matters more than people think On a Lindhaus the bag is not just a sack — it is the first stage of the filtration. A cheap copy with thinner paper lets fine dust through to the motor filter, which then clogs early and costs you suction. Lindhaus’s own bag is rated at 98.28% down to 0.3 micron on its own, before the air even reaches the exhaust filter. The two exhaust filters in the box are meant to be changed as you work through the bags — fit a fresh one roughly halfway and again at the end. That is the part most owners forget, and it is the usual reason a good machine starts to smell. How often should I change the bag? In an average home, every six to eight weeks. A box of eight is roughly a year. In a business, expect to go through them a good deal faster — the machine will tell you, because suction drops off before the bag is truly full. Is this the same bag as the PH4? No, and that is the single most common wrong order on a Lindhaus. A4 comes in eights and fits the Activa, Diamante and Dynamic. PH4/L4 comes in tens and fits the RX eco FORCE, HEALTHCARE Pro and CH Pro. What about my Valzer or LB3? Different bag again — those take the Lindhaus LB3 bag pack, which is a microfiber bag and comes with a HEPA filter. Are the two included filters HEPA? No. They are electrostatic exhaust micro-filters, which is what these machines use as standard. Certified HEPA is a separate optional filter for the machine — call 888-565-6163 if you want one. Can I use a generic bag instead? They exist and they are cheaper. They also tend to use thinner paper, which pushes more dust onto the motor filter and shortens its life. On a machine that costs several hundred dollars and is built to last twenty years, we would use the real thing. See every Lindhaus we carry on our Lindhaus brand page, or browse the Lindhaus vacuums.
