Our Verdict
The Nuna Pipa Aire is a lightweight version of the popular Pipa RX. This version weighs almost a pound and a half less than its bigger brother, but still earns an exceptionally high score in crash-test analysis. With some of the lowest g-forces we've ever seen recorded during our commissioned tests, it is hard to be mad at this sleek-looking seat. The Aire is also compatible with many popular strollers, making it a potential contender for those who need a stroller at their destination. The Aire is cheaper than other Nuna seats, but it is still on the higher end price-wise. We also didn't think it was as easy to install as some others, especially using the vehicle belt on the base. While we like this seat, we think there is a niche audience for it (those looking for a cheaper Nuna with good crash analysis), we think some families will be happier with another choice, both more and less expensive.

Our Analysis and Test Results

Crash Testing
The Pipa Aire is one of the highest-scoring infant seats for crash test analysis, with few seats performing better in our commissioned crash tests.
While it doesn't quite match other Nuna car seats we've tested, the Aire still earns some of the lowest sensor g-force readings in the group (less is more, people). Whether it is the HIC (head sensor) or the chest clip sensor, our commissioned crash testing showed impressive results. The HIC results are among the lowest we've ever seen, and the chest clip results were beaten only by a couple of contenders (including a Nuna brother).

While every seat in our review should be considered safe and assumed to have passed the federal minimum guidelines, we ran our test a little faster and on a sled that more closely mimics modern vehicles. We are looking for standout seats that perform better than average under these conditions. The Aire is one of these seats and may offer an additional margin of protection compared to the average seat.

Ease of Installation LATCH
Installing the Aire with LATCH is better than average, but it isn't as simple as some competitors, even those by Nuna.
The seat has flip-out rigid LATCH connectors. It comes with LATCH guides, which can be useful if your vehicle anchors are harder to find or the gap between the seatback and bottom is tight.
Installing the Nuna Aire really is as simple as this video makes it seem. Credit: Matt Lighthart
Folding down the connectors is easy, and they push onto the anchors without much resistance. We could hear a reassuring click, and the color indicator on the connectors shifted from red to green, indicating it was good to go. We love that there is nothing to tighten here, making it a good choice for anyone worried about tightening straps or having enough strength to get the job done.
Once installed, it didn't wiggle as much as some other rigid LATCH connectors, and overall, it feels pretty stable. Uninstalling is pretty easy with dual release buttons on either side of the LATCH connectors on the base. They are a little stiff to press, but once they release, the connectors are easy to fold up for storage. The load leg is the real devil here because you have to find the right length for storing it, and ours didn't always want to stay inside the base.
The recline adjustment to help find a level installation is dated and simplistic, and it needs to be adjusted before you attach the LATCH connectors, because you can't adjust it once it is installed. Credit: Matt Lighthart
Recline Adjustment
The recline adjustment is a kick-out leg on the bottom of the base. It flips out with little fn fare, and you need to determine that you need it before you connect the LATCH, or it is really hard to do. It seems pretty basic and not refined for a seat in this price bracket. It is easy to operate, but it feels like an afterthought to us, more so than an intentional design to make installation easier. There are two recline positions.

The base has a bubble level indicator on each side. They work well, and we like that you can determine whether the base is level on both sides.

Load Leg
It is hard to say if a load leg impacts safety in traditional crash testing, as we've seen it go both ways. This means it is likely something that comes down to many mitigating factors we simply can't account for or nail down. While we like the idea and see how they could be effective, we think parents should rely more on the crash test analysis results than on any one single feature or claim from the manufacturer.

This load leg is frustrating to move around, as it tends to spontaneously fall off the base's bottom. If you barely even touch it, the darn things shoot out and fall.

Ease of Installation - Belt
Installing the Nuna base with the vehicle belt is one of the most challenging methods. This makes it a less compelling contender for those who might need to install it with the belt rather than the LATCH connectors.
If you want to install your seat in the middle of the back seat, then this is an important test because most cars don't have LATCH anchors for the middle seat.

The Aire lockoff works well, but we wish it were somewhat longer for better leverage. Credit: Matt Lighthart
Treading the belt through the base is fairly easy, and the lock-off works well. Aside from a little effort to tighten the belt, we didn't have any trouble. It almost doesn't get easier to install a base with the vehicle belt than this. We wish the lock-off were a little longer to give more leverage on the belt, but it works well.

The final installation feels very stable with some of the least amount of play or wiggle in the group.
Ease of Installation - w/o the Base
Installing the Aire without the base is about as difficult as installing the LATCH, with better-than-average performance in our tests.
The Aire uses the American or European belt installation when installing without the base. The pathway for both is color-coded, easy to follow, and there is a line decal sticker to help you get the level right.

We had trouble with the back of the canopy poofing out from the seat shell, which made it difficult to thread the vehicle belt's shoulder portion through the rear guide. It is removable, but it feels like something that could have been easy to avoid during the design phase if someone had paid closer attention to real-world experience.

It feels pretty stable when installed, and we preferred the European method to the American one, but we recommend following the manufacturer's guidelines no matter which route you take.

Ease of Use
The Aire scored below average for ease of use. If it were a more reasonably priced option, this might feel acceptable, but given the higher price, it is disappointing.
While nothing here is intrinsically challenging to use, it can't hold a candle to some of the easier options in the test group.

Buckle
The buckle is pretty basic with no outstanding qualities, but the crotch pad is super poofy and covers much of it, making it difficult to get to and harder to press than it needs to be. We appreciate the inclusion of strap padding, but not when it impacts functionality. If the padding was secured to the seat or the cover, we think this would be much easier.
The chest clip has side guides that need to be lined up just so in order to work without issue. It slides well enough, and the release button is easy to press. Overall, it might take some practice to dial in the motion, but it wasn't hard.

Harness Tightening/Loosening
The harness-tightening strap on the Aire moves smoothly with minimal resistance. The pull strap has a sewn loop on the end, which isn't our favorite, but perhaps some parents will find it useful. The release button is just inside the opening and is easy to access. We think it is more long-fingernail friendly than many other contenders, and the release feels smooth.
Harness Adjustment
Nuna has once again failed to offer us a non-rethread car seat, and at this price, it feels disappointing. Sure, you may only need to adjust the shoulder strap height once or twice, and rethreading isn't difficult, but it does require removing your baby from the carrier and the carrier from the car, and we worry parents will skip or forget to do it because it takes time no one has. Being able to smoothly shift a headrest assembly up when you realize a need is far easier. There is only one crotch strap position and three shoulder strap positions (far fewer than the highest in the group that offers 25!).
Carrier to Base Connection
Putting the carrier on the base isn't as seamless as many competitors. It sort of gets hung up on something and isn't perfect. It is also one of the few options we've seen where the release button is on the base rather than the carrier.
The carrier release handle is located on the Aire's base, not on the carrier, where we usually find it. Credit: Matt Lighthart
When it is on the carrier portion, we can typically use it as a lifting point to remove the carrier. Here, we had to unlock it with one hand while lifting with the other, then quickly move our hand to support the carrier's other end. It seemed unnecessarily convoluted.
The Aire's handle can collide with the canopy, causing movement problems. Credit: Matt Lighthart
Handle
The handle has 3 positions and a half position suitable for lifting the carrier out of the car, but is not intended for any other use. The handle rotates much like most of the competition after unlocking using dual buttons on either side at a central pivot point.
The flat shape of the Aire's handlebar isn't as comfortable as those that are more rounded. Credit: Matt Lighthart
It is easy to do, but the canopy/handle rubbing that happens when each part is in just the right spot is a bummer at this price point and it feels like a design flaw. Given that many competitors have managed to design a canopy and handle that never touch, leaving ample room for hands and arms, it feels like a small ask that could be easily granted.

Canopy
The canopy on the Aire is better than average, and with the handle up, there is no collision. However, as the handle passes over the open canopy, it rubs against the zippered extension panel. The ribs of the canopy are somewhat flexible, so you can get your whole arm in, but it does bend the canopy to the side. The fabric bunches up and pooches a bit when closed, and there is some friction between the handle and fabric.

LATCH and Manual Storage
The LATCH connectors are rigid LATCH extensions that fold down from the base. When not in use, they fold back up and sit close to the base and out of the way. The design locks in place and releases with a button push. It works well, but we'd love a more hidden design or one where spilled liquids wouldn't gunk up the rotation.
The Aire's manual is stored in a fabric pocket on the carrier, so you'll have it nearby even if you travel without the base. Credit: Matt Lighthart
The Aire manual has a storage pocket on the carrier seat rather than on the base, where most competitors place it. We like that it goes with you even if you aren't using the base.

The fabric on the Aire is soft enough, but not the softest in the group. Credit: Matt Lighthart

Fabric and Padding
The fabric fit is good all around and stretches somewhat in the seat with a baby inside. It is softer than some competitors, with softer inserts than the main seat.
The base padding is lackluster and not as thick as we would have hoped for this price. It compresses easily and lacks as much support as others. Still, it is more than cheaper competitors that offer next to nothing. The inserts have far more padding, which is nice for smaller infants, but the headrest padding is only a single layer, and the comfort difference between the supportive inserts and the base seat is noticeable.
While the handlebar on the Aire doesn't directly touch the canopy when both are up, it is close and will rub the ribs at certain points when moving. Credit: Matt Lighthart
Handle and Canopy
The handle has a leather grip in the center, but the bar is not the best shape. It has more pronounced edges that aren't as comfortable to hold as bars that are more round.
The canopy is relatively large before you use the extension panel, and without it, the lower sun could shine on the passenger's face. It is taught and feels durable with ventilation included in the extension panel.
Shell
The shell is average and very similar to most of the other competitors. It has a clean overall look with some warning and instructional stickers on the side. It feels sturdy, and we didn't find any rough edges or places for gunk to hide.
The Aire is significantly lighter than the average seat. Credit: Matt Lighthart
Weight/Size
The Pipa Aire is the lighter Nuna brother with a weight of only 7.1 lbs. While a couple of carriers weigh less, it is hard to find a seat that is lightweight and has exceptional crash test results.
If you never plan to carry your baby around in their carrier, the weight might be less important to you. Pairing your car seat with a stroller or using a baby carrier instead could make this test less important in your decision-making.
The Aire is compatible with Nuna strollers and several other top-ranked options from other manufacturers (with adapters). Shown here with the Nuna Mixx Next. Credit: Matt Lighthart
Should You Buy the Pipa Aire?
Yes! Depending on your needs, the Aire is an excellent car seat suitable for many families. This seat has a lower price than the similar Nuna Pipa RX, and a lighter carrier weight with similar crash test analysis results, making it a notable Nuna that can save you money. While it is somewhat more challenging to install in every method than its more expensive brother, and the quality isn't quite as good, we think most parents won't know what they are missing. If you hope to pair your carrier with a stroller, the Nuna is also highly compatible with many popular strollers from Nuna and other brands like UPPAbaby, with the purchase of adapters.
What Other Infant Car Seat Should You Consider?
While the Pipa Aire is an impressive, high-ranking seat, it might not be the right option for everyone. If the best absolute crash test results are top of mind, the Pipa RX is the obvious choice. It is easy to install by any method and offers top-tier quality and comfort. If you want to spend less and get more, the Romer Juni earned similar crash analysis results to the Aire, but costs about $40 less. It is easier to install with LATCH and the vehicle belt, but the carrier is heavier, and it could be a pain if you regularly plan to carry your little one in it.
