If you're unsure, examine if your vacuum comes with a HEPA bag or filter. This implies it can eliminate at least 99.97 percent of allergens, such as mold, dander, and dust, from your house.
All the better if it comes with a certificate from the Asthma and Allergy Foundation of America. Some versions don't have HEPA filters, but they do have advanced filtering systems that are supposed to be as efficient as HEPA filters.
Dirt and dust tend to become embedded in furniture fibers and carpets, necessitating the use of a powerful vacuum with the appropriate attachments and functions. Look for a vacuum with changeable height settings to accommodate various piles if your home is carpeted or has area rugs in multiple areas.
When cleaning carpeting composed of natural or looped fibers, Witulski recommends using a vacuum without a beater bar. Find a model that includes an upholstery brush if you have a carpet.
If you have primarily hard or bare floors in your home, search for a vacuum with a gentle cleaning brush that won't spread debris.
Bagged vs. Bagless
Because they don't require new replacement bags on a regular basis, bagless vacuums are often the less expensive alternative over time. Bagged vacuums, despite the added cost, may provide a level of security for allergies patients that bagless ones cannot.
"Bagged vacuums are exceptionally hygienic and securely contain dirt and debris," adds Melissa Witulski, Merry Maids' brand standards manager. Even when it's time to throw away and replace the bag, all that dust and dander is safely locked away. A bagged vacuum will provide you some much-needed peace of mind if you're worried about cleaning up your new vacuum and re-releasing allergens into your home.
