After 16 months and more than 8 blowouts, Kirby HEPA bags keep being useful even though the particle count went up by 500%. Airflow was essentially unaffected at about a 2.1% loss.
excellent test you've done here....I've shared your findings with others who balked at this idea. For those of you who can't get discounted hepa bags for their vacuums, this is a nice alternative(albeit a bit dusty).
hands are starting to grow to big to fit through the hole to turn kirby white or charcoal bags as all kirby bags except paper bags-are same polypropylene nonwoven material aka turn inside out and vigoruosly shakeout the dust and clap it into a trash can... how did u get urs to turn inside out?
My 1973 Kirby Classic Omega still has the original cloth shakeout bag that it came equipped with. It’s been dry cleaned a few times. In forty five years I’ve only replaced belts and two brush rollers. I have two Mighty Mites (One Sanitaire and one Eureka outfitted with the WW accessories that the Sanitaires come with) one one each floor. I have HEPA after filters attached to each one and replace them every nine months. Not only does it save me a great deal of money every year but though the Mighty Mites have 12amp motors their bag chambers are small. Using a cloth bag enables them to work with my WW turbonozzles. I think that the aftermarket available synthetic cloth HEPA diaper bags might also enable the use of a turbo nozzle.I use my Might Mites daily and my Kirby every two weeks when I deep clean and move furniture. I have an Oreck XL on my first floor and a Maytag M500 that I use daily. If they were available with shakeout bags and their outer bags were easily washable I’d go that route. I have an Electrolux Silverado, a Swedish Electrolux UltraSilencer and a Miele Pure Suction all of which use HEPA bags and each cost about $50.00 per year to run. I use them on my deep cleaning days when I move furniture. In using the Mighty Mights for daily use the need for bag and filter changes in those machines is greatly reduced.
