Bagged vs. Bagless
When purchasing a vacuum cleaner, a common question is whether you should purchase a bagged or bagless model. A couple of details to help with your purchase include:
- Allergy Concerns: Bagged vacuum cleaners release less dust into the air, making it more allergy friendly.
- Cost: Although bagless vacuum cleaners have filters that will eventually require cleaning or replacement, the cost impact of not having to replace the bag each time the dust compartment is full makes bagless vacuum cleaners a bit more cost-effective.
Common Vacuum Terms
Agitator: Brush at base of the vacuum that moves debris up to be suctioned into a bag or canister.
Belt: The belt causes the brushes to rotate and process debris.
Cleaning path: The cleaning path is determined by the width of the base of the vacuum cleaner — the wider the base the larger the cleaning path.
Filtration: Filtration systems help remove dust mites from floors and furniture. This is ideal for reducing household allergens.
HEPA air filter: High Efficiency Particulate Air (HEPA) filters are extended-surface filters that capture up to 99% of all dust particles.
Motor: Measured in amps, watts, and volts, the motor power determines the suction of the vacuum. Greater suction power means you spend less time cleaning your floors.
Motor protection system: A safeguard that protects a vacuum motor from overheating.
Retractable cord: An feature that automatically winds the cord for storage in the machine.
Self-propelled motor: A feature that propels the vacuum on its own for easier maneuvering.

Don't Sweat It! 9 Tips for Getting Air Conditioning on a Budget
Frequently Asked Questions
Do ceiling fans save money?
Running a fan is significantly cheaper than running an A/C unit because you can target rooms you're utilizing instead of your entire home.
However, a more important question is whether a fan meets your cooling needs. A fan alone may or may not keep you cool, so the trick is to use the fan in conjunction with your air conditioning. Fans do not actually cool the air, so if you’re stuck in an 85-degree room you’re just having 85-degree air blowing on your skin.
This trick can save you hundreds of dollars each year, so in short, yes, fans definitely save money! Check out this blog post for more info!
Do air purifiers work?
A machine that quietly hums in the background while cleaning your air may sound too good to be true. But if you’re an allergy or asthma sufferer, a quality air purifier may be worth the investment.
This study concludes that air filtration through HEPA purifiers are useful for allergy sufferers, but notes the effectiveness is limited to one room instead of a whole house. While air purifiers are limited in what they can clean from the air (dust, smoke, pollen), the added relief can aid those who have tried many other solutions.
It’s important to note that air purifiers are not very effective, if at all, in cleaning out mold or VOCs that accumulate in the air from adhesives, paints, or cleaning products.
Humidifier vs. Dehumidifier: Which do I need and why?
Humidity regulation, whether by a humidifier or dehumidifier, helps with comfort levels in your home. According to Richmond’s Air Heating & Air Conditioning , a good humidity level for the home is between 35% and 45%. You can measure this with a hygrometer or you can try a few tricks like the one found here for low humidity measurements, or here for high humidity measurements.
High and low humidity can each create different issues in your home and body. Low humidity can damage your furniture, floors, and doors, causing them to crack. It can even cause caulk or glue to shrink, creating gaps that allow air to leak out. Worse, high humidity affects sleep , and exacerbates breathing problems like asthma by creating a breeding ground for mold and other allergens .
Low humidity is also problematic, causing dry skin, nasal irritation, and even spreading the flu .
