Overview:
Get a bundle of 3 Aspen high-performance air purifiers to improve the air quality in your whole home. One Aspen air purifier covers about 1,500 square feet (depending on a variety of factors) so 3 is optimal for homes from 2,500 - 4,500 square feet. This is the ideal solution for those who suffer from allergies to dust mites, pollen, pet dander, mold, and any airborne pollutant.
Aspen is a high-performance air purifier with true HEPA and activated carbon filtration, high airflow, and exceptional efficiency. It is designed and assembled in America with a quiet and efficient German EC fan motor that uses 85% less electricity than AC fans in most other units. Aspen is the best choice for asthma and allergy sufferers and those who demand the highest indoor air quality.
Key Features:
- 3 Stage Air Filtration
- Allergy Filter: MERV 14 rated and removes allergy and asthma causing particles including dust, pollen, pet dander, mold spores, dust mite droppings, asbestos, fiberglass insulation, sneeze droplets, and other PM10 and PM2.5 pollutants. Independently tested according to ASHRAE 52.2 standards.
- Activated Carbon Filter: Custom engineered with 3.3lbs of activated carbon with microscopic pores that capture and remove odors, formaldehyde, tobacco smoke, and VOCs from sources like cleaning products, paint, and other chemicals.
- Microparticle HEPA Filter: Hospital grade filter removes 99.99% of particles down to 1.0 micron and 99.97% of particles down to 0.1 microns, which includes smoke, bacteria, viruses, smog, radioactive fallout, and ultrafine dust. Independently tested according to IEST-RP-CC001.6 standards.
- Exceptional Efficiency: A German made EC fan motor moves air using up to 85% less energy* than AC fans in other air purifiers, so you save money and electricity.
- High Airflow: Aspen is capable of moving a high volume of air with an AHAM Clean Air Delivery Rate (CADR) of 442 CFM for pollen and 373 CFM for smoke. The airflow pattern distributes the clean air throughout the room better than units that "diffuse" the air in all directions. Aspen's airflow does not suck the same clean air right back into the unit, which allows it to clean more of the air in the room by creating a more efficient air circulation pattern.
- 6 Fan Speeds: Choose between 6 fan speeds from whisper quiet for sleeping to maximum air cleaning performance.
- Simple User Interface: Designed to be easy to use so you can spend less time fumbling with fancy menus and more time enjoying your clean air. No bluetooth or wifi so you don't have to worry about EMFs or connectivity issues.
- 100% Safe: Does not produce harmful ozone or contain dangerous UV lights or ionizers.
- Easy Filter Replacement: A simple design makes changing filters easy and quick.
- Covid-19 Effective: The Covid-19 virus is approximately 0.12 microns. Aspen removes more than 99.97% of particles this size on the first pass through the unit alone.
* Aspen uses over 85% less electricity than the closest competitor with similar filtration performance at a normal operating airflow of 100 CFM.

Very nearly the perfect frother for all your basic frothing & mixing needs
Color: Black
There are a lot of middle-of-the-road frothers out there. I've been through a few of them in my recent search for something that could mix and froth well, without taking up any more outlets in my basement kitchen. Of the three Maestri frothers I've tried so far, this one wins the race by a nose.
Most recently, these Maestri frothers come in basically three versions: A single-speed @ 8000 RPM, a two-speed @8000/5500 RPM, and this stepless variable-speed version. Aside from that, the only real difference in recent version pack-outs is which attachments they come with.
Look over the reviews of the single-speed version and you'll find that while it can and does froth well, it starts at a single, high speed and gets there fast. This makes it pretty easy to spin liquid right out of most common cups and mugs.
There is a two-speed version, but it's harder to find, only comes in one color (Grape Purple), and while it's much better than the Maestri single-speed, it still has a couple of quirks that make this variable-speed version win out.
This mixes and froths whole milk, half-and-half, or heavy whipping cream, or just about anything else very well. Like all frothers, it takes a little time to learn its nuances and nail down the technique, this will definitely get you there.
The best feature of this is easily the speed control. Turn the knob to turn it on at a low speed that's great to get things started, then turn the knob to crank up the speed just enough to do what you need, whether that's mixing or frothing. The low starting speed makes it easy to keep things under control without undue spilling, and the max speed is more than enough to make quick work of getting your froth on.
There are really only two complaints I have with this stepless, variable speed version:
- I'd really like to have a Press On / Release Off button in addition to the Speed Control knob. More than one time have I gone to turn this off, only to spin the knob the wrong way and crank the speed up to ludicrous, sloshing liquid on the counter. Being able to turn it Off just by letting go of the button would be quick and easy. This configuration would allow using a preferred speed right from the start, while still allowing speed to be adjusted on-the-fly when needed.
- Give it a bigger battery. It would cost mere pennies to give this a 2000mAH+ instead of a 1200mAH battery, and I can't think of any reasonable downside to that.
- Give the motor a little more torque. It's fairly easy for the current motor, at any speed, to get bogged down in a thick protein powder mix, or when pressing the frother or other attachment a bit too hard into the bottom or side of the frothing container. A bit more "oomph" would prevent that.
I really like the overall design and features of thes Maestri frothers better than many other, cheaper versions. This variable-speed version is pretty great as it is and probably the one I would recommend over the single- or two-speed, for most people. But I often find myself using two hands -- one to hold it steady, and the other to turn it on and tweak the knob to the desired speed(s) -- for a device that should arguably need only one hand to use. Just a couple of minor tweaks as noted above would make this the overall best frother of its type that I've used.

Hands down, the BEST handheld frother I've ever used!
Color: Black
Hands down, the BEST handheld frother I've ever used! I got the black one, but any color will have the same results.
Over the past 12 years or so, I've used so many different handheld frothers and they've ALL fallen short of expectations for quality, longevity, power, features, and usability.
I've used everything from cheap, $15 models to $50+ models and everything in-between. Some with fancy attachments for various types of mixing, frothing, beating, whipping, etc. Some with rechargeable batteries, some without. Some AC powered, some with fixed whisks, some with detachable/replaceable whisks, some with stands, etc. NONE have been spectacular. Most broke within 6 months and got tossed. ALL were major disappointments in the end, including the "revered" Zulay models of which I tried several.
I finally found this Maestri House branded, variable speed frother with detachable / replaceable whisks and got one to try. I was literally on Cloud Nine the first time I turned it on. Like, WOW! Not only was it FAST on the highest speed, but it was powerful enough to churn right through milk, eggs, cream, etc, without bogging down like many others.
This thing makes milk froth like a milkshake and Matcha Lattes like nothing else I've ever experienced. I used to have to sift my Matcha, then whisk it in hot water, then froth milk and then blend them together to make the perfect latte. and if the milk was cold (my preference), pre-whisking in hot water was a must to avoid lumps. However, with THIS frother? I literally pour my milk into a tall tumbler, drop in un-sifted Matcha powder, and spin up the Maestri House frother at first on a medium low speed to get it mixed, then jump straight to the highest speed to really whip that milk and match up. After about 30-45 seconds, I've got the thickest, richest, smoothest, most aerated latte around. And NO LUMPS at all!!! What a time and dish saver!
And cleaning? I just run it under hot running water to get the shaft cleaned and then spin it up in a dish with hot running water for a few moments, then spin it on high for a few seconds in the air to dry it off instantly.
Now, I'll be honest here, too. The specs say it can go months on a charge, using it for a couple minutes a couple times daily. Well, I guess it could do that and still spin. But I use it FULL SPEED, churning hard for at least a minute a couple times per day. After about 2 weeks, I can start to notice a speed reduction so I just plug it back in on the charger. All things considered, this is still better than all the other handheld frothers I've used over the years.
After using the heck out of this thing for the past 7 months, I've even decided to start selling these in our Japanese gift shop. The manufacturer is has been very responsive both in customer support (I called them about an issue I thought I was having, and they called me back with a couple hours even though I didn't leave voicemail when they didn't answer right away) and in reseller support. I have to give these guys an A+ for responsiveness and quick resolution when problems might arise.
HIGHLY recommended!!

Great Addition!
Color: Black
Why did you pick this product vs others?:
I just started a powdered drink routine recently and was having a difficult time mixing it with water. I would consistently end up with small nuggets of mix making it unenjoyable to drink. I knew I needed a mixer and was glad I found this device when I did. It works perfectly! I like the fact that it comes with its own stand and included two mixing heads. It is solid, well-designed, and you can feel the quality when you pick it up. The variable speed of the mixer is perfect for ensuring that everything is blended well. I haven’t used it to “froth” anything yet, at least not on purpose, but I accidentally found out that it can do that well. This is a great addition to our kitchen and is very easy to wash after use. So far…no issues. Highly recommend for those of you looking for the right tool to make sure those protein mixes aren’t full of unmixed nuggets.

Low foam
Color: Black
Love this frother. It is great quality and the turn speed is amazing. My only issue is this. It comes w 2 wands and they are both singles. The single is great for stirring things up. It does not make a lot of froth and for some things it’s perfect but sometimes I like a lot of froth and I wish it either came w a single and a double or you could purchase a double separately to intermix. I don’t want to buy a whole other unit just for the double. I wrote to them bc the double frother they sell doesn’t look as good as this one but sometimes a girl needs a lot of foam and sometimes th stirring is perfect.
